What is an object in Ruby?
Function object
In Ruby, several objects can be considered function objects, in particular Method and Proc objects. Ruby also has two kinds of objects that can be thought of as semi-function objects: UnboundMethod and block. UnboundMethods must first be bound to an object (thus becoming a Method) before they can be used as a function object. Blocks can be called like function objects, but to be used in any other capacity as an object (e.g. passed as an argument) they must first be converted to a Proc. More recently, symbols (accessed via the literal unary indicator codice_35) can also be converted to codice_36s. Using Ruby's unary codice_37 operator—equivalent to calling codice_38 on an object, and assuming that method exists—the Ruby Extensions Project created a simple hack.
Sigil (computer programming)
In Ruby, ordinary variables lack sigils, but "codice_2" is prefixed to global variables, "codice_6" is prefixed to instance variables, and "codice_42" is prefixed to class variables. Ruby also uses (strictly conventional) suffix sigils: "codice_11" indicates a predicate method returning (usually) a boolean value; and "codice_44" indicates that the method modifies the object it acts on as a side effect.
Anonymous function
In R the anonymous functions are defined using the syntax codice_87 .
Ruby supports anonymous functions by using a syntactical structure called "block". There are two data types for blocks in Ruby. codice_88s behave similarly to closures, whereas codice_89s behave more analogous to an anonymous function. When passed to a method, a block is converted into a Proc in some circumstances.
RubyCocoa
RubyCocoa is a Mac OS X framework that provides a bridge between the Ruby and the Objective-C programming languages, allowing the user to manipulate Objective-C objects from Ruby, and vice versa. It makes it possible to write a Cocoa application completely in Ruby as well as to write an application that mixes Ruby and Objective-C code. An Apple project called MacRuby was under development to replace RubyCocoa in 2008. A proprietary spin-off called RubyMotion was subsequently released in 2012, available for iOS, OS X and Android.
Lego Mindstorms NXT
Ruby-nxt is a library to program the NXT for the Ruby programming language. Unlike the other languages for the NXT, the code is not compiled to a binary file. Instead the code is directly transmitted to the NXT via a Bluetooth connection.
Factory (object-oriented programming)
For example, in Python, the codice_2 class has a constructor which creates an object of type codice_3 whose default values are produced by invoking a factory. The factory is passed as an argument to the constructor, and can itself be a constructor, or any thing that behaves like a constructor – a callable object that returns an object, i.e., a factory. For example, using the codice_4 constructor for lists:
Factory objects are used in situations where getting hold of an object of a particular kind is a more complex process than simply creating a new object, notably if complex allocation or initialization is desired. Some of the processes required in the creation of an object include determining which object to create, managing the lifetime of the object, and managing specialized build-up and tear-down concerns of the object. The factory object might decide to create the object's class (if applicable) dynamically, return it from an object pool, do complex configuration on the object, or other things. Similarly, using this definition, a singleton implemented by the singleton pattern is a formal factory – it returns an object, but does not create new objects beyond the single instance.
Ruby Gloom
Ruby is a young girl who can find happiness in anything. "Look on the bright side" is her mantra. There isn't a single thing in the world that gets her down or a single negative that she can't turn into a positive. Her positive attitude allows her to act as the voice of reason in the mansion when her friends lose focus on real issues. Ruby has a crush on one of her friends, Skull Boy, and nearly reveals her feelings to him in the episode "Sunny Daze", when the two of them are trapped in a cave. Her positive outlook also makes Ruby very loyal to her friends. She likes to write in her diary and knit. Voiced by Sarah Gadon.
Function object
Because of the variety of forms, the term Functor is not generally used in Ruby to mean a Function object.
Just a type of dispatch delegation introduced by the Ruby Facets project is named as Functor. The most basic definition of which is:
Oobi (toy)
Physically, an Oobi is a bright orange oblong spheroid with a slit, an addressing area, and big painted-on eyes. They were sold in packs of three. The original purchaser was to write an address on the address area, place a folded message inside, and leave the toy somewhere public to be found. Instructions to the finder were written on the Oobi's top: "I'm oobi. I contain a message to another human being. Please further my journey an inch, a foot, or a mile. Add a note, if you wish. Then help me to the next nice person like yourself! I'm on my way to ... Please don't confine me to a mailbox."
Ruby (programming language)
[[RubyGems]] is Ruby's package manager. A Ruby package is called a "gem" and can easily be installed via the command line. Most gems are libraries, though a few exist that are applications, such as [[integrated development environment|IDEs]]. There are over 9,000 Ruby gems hosted on RubyGems.org.

It is also possible to specify that the exception object be made available to the handler clause:
Data, context and interaction
A Role is a stateless programming construct that corresponds to the end user's mental model of some entity in the system. A Role represents a collection of responsibilities. Whereas vernacular object-oriented programming speaks of objects or classes as the loci of responsibilities, DCI ascribes them to Roles. An object participating in a use case has responsibilities: those that it takes on as a result of playing a particular Role. Most modern programming languages have a way to express Roles, and to express the injection of Role methods into objects, and implementation techniques vary depending on the language. The injection can be fully dynamic at run-time in languages like Ruby and Python; it is more static in languages like Smalltalk-Squeak, Scala and C++. The Qi4j programming environment offers a way to express Role method injection into Java objects. Java 8 default method on interfaces can be used to implement Roles in a typesafe way.

A code block can be passed to a method as an optional block argument. Many built-in methods have such arguments:
Linguistic relativity
In a 2003 presentation at an open source convention, Yukihiro Matsumoto, creator of the programming language Ruby, said that one of his inspirations for developing the language was the science fiction novel "Babel-17", based on the Sapir–Whorf Hypothesis.
Capybara (software)
Capybara is a Ruby library (also referred to as a gem) that is used with an underlying web-based driver. It consists of a user-friendly DSL (Domain Specific Language) which describe actions that are executed by the underlying web driver.
Ruby License
The Ruby License is a Free and Open Source license applied to the Ruby programming language and also available to be used in other projects. It is approved by the Free Software Foundation although it has not been approved Open Source by the Open Source Initiative.
Ruby (programming language)
The following code defines a class named codice_26. In addition to codice_27, the usual constructor to create new objects, it has two methods: one to override the codice_28 comparison operator (so codice_29 can sort by age) and the other to override the codice_30 method (so codice_31 can format its output). Here, codice_12 is an example of metaprogramming in Ruby: codice_33 defines getter and setter methods of instance variables, but codice_12 only getter methods. The last evaluated statement in a method is its return value, allowing the omission of an explicit codice_35 statement.
RubyGems
RubyGems is a package manager for the Ruby programming language that provides a standard format for distributing Ruby programs and libraries (in a self-contained format called a "gem"), a tool designed to easily manage the installation of gems, and a server for distributing them. It was created by Chad Fowler and Richard Kilmer during RubyConf 2004.
Ruby (programming language)
Ruby has been described as a multi-paradigm programming language: it allows procedural programming (defining functions/variables outside classes makes them part of the root, 'self' Object), with object orientation (everything is an object) or functional programming (it has anonymous functions, closures, and continuations; statements all have values, and functions return the last evaluation). It has support for introspection, reflection and metaprogramming, as well as support for interpreter-based threads. Ruby features dynamic typing, and supports parametric polymorphism.
Child of the Moon
Spencer comes to the police station and accuses Ruby of the murder. After David refuses Spencer's demand that Ruby be turned over to the will of the townspeople, Spencer denounces David and Ruby to an angry mob that then breaks into the station, only to find that Ruby is gone. She is at the library, where Belle (Emilie de Ravin) has agreed to hide her. Over Ruby's warnings, Belle plans to stay through the night with a chained Ruby. But Ruby instead traps Belle and goes to face the mob, believing she deserves death. Granny's tracking skills lead David to uncover Ruby's hood and the real murder weapon, an axe, in the trunk of a car registered to Spencer. Spencer and the mob corner Ruby in her wolf form and Spencer points his gun at her, but Granny disarms Spencer with a crossbow. David identifies Spencer as the murderer and demands that the mob stand down. He calms Ruby and puts the hood over her, restoring her human form. After Spencer flees, David and Ruby pursue him but catch him only after he destroys Jefferson's hat in a fire; David points his gun at him, but lets him live. At the loft, Ruby reassures David that they'll find a way to bring his family home. She leaves the hood with him so she can run free as a wolf.
Distributed object
Distributed Ruby (DRb) is a framework for distributed objects using the Ruby programming language.
QML
Objects are specified by their type, followed by a pair of braces. Object types always begin with a capital letter. In the example above, there are two objects, a Rectangle; and its child, an Image. Between the braces, one can specify information about the object, such as its properties.
Properties are specified as property: value. In the example above, we can see the Image has a property named source, which has been assigned the value codice_1. The property and its value are separated by a colon.

Robotics middleware
Urbi is an open source cross-platform software platform in C++ used to develop applications for robotics and complex systems. It is based on the UObject distributed C++ component architecture. It also includes the urbiscript orchestration language which is a parallel and event-driven script language. UObject components can be plugged into urbiscript and appear as native objects that can be scripted to specify their interactions and data exchanges. UObjects can be linked to the urbiscript interpreter, or executed as autonomous processes in "remote" mode, either in another thread, another process, a machine on the local network, or a machine on a distant network.
Ruby (programming language)
Already present at this stage of development were many of the features familiar in later releases of Ruby, including object-oriented design, classes with inheritance, mixins, iterators, closures, exception handling and garbage collection.
Class (computer programming)
An open class is one that can be changed. Typically, an executable program cannot be changed by customers. Developers can often change some classes, but typically cannot change standard or built-in ones. In Ruby, all classes are open. In Python, classes can be created at runtime, and all can be modified afterwards. Objective-C categories permit the programmer to add methods to an existing class without the need to recompile that class or even have access to its source code.
Ruby Thursday
Ruby begins running weapons procurement scams against A.I.M. She partners with and becomes romantically involved with the Answer. After having stolen money from A.I.M. on five different occasions, A.I.M. hires the assassin Bullseye to kill Ruby. He uses her relationship with Answer to draw her out of hiding and throws the Rolling Stones album "Flashpoint" (which contains the song "Ruby Tuesday") into her chest apparently killing the biological portion of her body. The Answer saves her head after Bullseye leaves in hopes of reviving her later.
Learning object
A learning object is "a collection of content items, practice items, and assessment items that are combined based on a single learning objective". The term is credited to Wayne Hodgins, and dates from a working group in 1994 bearing the name. The concept encompassed by 'Learning Objects' is known by numerous other terms, including: content objects, chunks, educational objects, information objects, intelligent objects, knowledge bits, knowledge objects, learning components, media objects, reusable curriculum components, nuggets, reusable information objects, reusable learning objects, testable reusable units of cognition, training components, and units of learning.
Immutable object
In object-oriented and functional programming, an immutable object (unchangeable object) is an object whose state cannot be modified after it is created. This is in contrast to a mutable object (changeable object), which can be modified after it is created. In some cases, an object is considered immutable even if some internally used attributes change, but the object's state appears unchanging from an external point of view. For example, an object that uses memoization to cache the results of expensive computations could still be considered an immutable object.
Ruby Document format
RD (Ruby Document) is a lightweight markup language
for writing Ruby-related documents.
It can be embedded in Ruby source code.
Ruby Blast
"Ruby Blast" and "Ruby Blast Adventures" are match 3 puzzle games in which players attempt to match three or more gems to help Ruby, the game’s protagonist, recover ancient artifacts. As players match gems, they dig deeper into a mine by activating power-ups. In the connected, multi-platform game, all progress including scores, gems, coins, levels and in-game currency is synchronized between the mobile and Web versions. Players view their friends’ scores and compete to rise to the top of the leaderboard. Both the mobile and Web versions enable players to compete in weekly tournaments and offer ways to help out their friends. The Web game also offers an Adventure Mode, in which players advance through multiple levels and have the ability to compete against other players globally for prizes.
Common Object Request Broker Architecture
This table presents the history of CORBA standard versions.
A servant is the invocation target containing methods for handling the remote method invocations. In the newer CORBA versions, the remote object (on the server side) is split into the object "(that is exposed to remote invocations)" and servant "(to which the former part forwards the method calls)". It can be one "servant" per remote "object", or the same servant can support several (possibly all) objects, associated with the given Portable Object Adapter. The "servant" for each "object" can be set or found "once and forever" (servant activation) or dynamically chosen each time the method on that object is invoked (servant location). Both servant locator and servant activator can forward the calls to another server. In total, this system provides a very powerful means to balance the load, distributing requests between several machines. In the object-oriented languages, both remote "object" and its "servant" are objects from the viewpoint of the object-oriented programming.
Pokémon Ruby and Sapphire
The basic mechanics of "Ruby" and "Sapphire" are largely the same as their predecessors'. As with all "Pokémon" games for hand-held consoles, gameplay is in third-person, overhead perspective and consists of three basic screens: a field map, in which the player navigates the main character; a battle screen; and the menu, in which the player configures their party, items, or gameplay settings. The player begins the game with one Pokémon, and can capture more using Poké Balls. The player can also use their Pokémon to battle other Pokémon. When the player encounters a wild Pokémon or is challenged by a trainer to a battle, the screen switches to a turn-based battle screen where the Pokémon fight. During battle, the player may fight, use an item, switch their active Pokémon, or flee (the last is not an option in battles against trainers). All Pokémon have hit points (HP); when a Pokémon's HP is reduced to zero, it faints and cannot battle until it is revived. If the player's Pokémon defeats the opposing Pokémon (causes it to faint), it receives experience points. After accumulating enough experience points, it may level up; most Pokémon evolve into a new species of Pokémon when they reach a certain level.
Ruby (programming language)
A method such as codice_18 can accept both a parameter and a block. The codice_18 method iterates over each member of a list, performing some function on it while retaining an aggregate. This is analogous to the codice_20 function in [[functional programming languages]]. For example:

Ruby 2.5.0 was released on Christmas Day in 2017. A few notable changes include:On top of that come a lot of performance improvements like faster block passing (3 times faster), faster Mutexes, faster ERB templates and improvements on some concatenation methods.
Thredded
Thredded is written in Ruby and can be used standalone or as part of an existing Ruby on Rails application.
Thredded's stated goals are to be feature-rich and simple.
Uniform access principle
Strictly speaking, Ruby does not follow Meyer's original UAP in that the syntax for accessing an attribute is different from the syntax for invoking a method. But here, the access for an attribute will always actually be through a function which is often automatically generated. So in essence, either type of access invokes a function and the language does follow Meyer's revised Uniform Access Principle.
Ruby (programming language)
By 1999, Ruby was known to work across many different [[operating system]]s, including NEWS-OS, SunOS, [[AIX]], [[SVR4]], [[Solaris (operating system)|Solaris]], [[NEC]] [[UP-UX]], [[NeXTSTEP]], BSD, Linux, [[Classic Mac OS|Mac OS]], [[DOS]], [[Windows (operating system)|Windows]], and [[BeOS]].
Ruby
Generally, gemstone-quality corundum in all shades of red, including pink, are called rubies. However, in the United States, a minimum color saturation must be met to be called a ruby; otherwise, the stone will be called a pink sapphire. Drawing a distinction between rubies and pink sapphires is relatively new, having arisen sometime in the 20th century. Often, the distinction between ruby and pink sapphire is not clear and can be debated. As a result of the difficulty and subjectiveness of such distinctions, trade organizations such as the International Colored Gemstone Association (ICGA) have adopted the broader definition for ruby which encompasses its lighter shades, including pink.
Equals sign
In Ruby, equality under codice_12 requires both operands to be of identical type, e.g. codice_9 is false. The codice_8 operator is flexible and may be defined arbitrarily for any given type. For example, a value of type codice_21 is a range of integers, such as codice_22. codice_23 is false, since the types are different (Range vs. Integer); however codice_24 is true, since codice_8 on codice_21 values means "inclusion in the range". Note that under these semantics, codice_8 is non-symmetric; e.g. codice_28 is false, since it is interpreted to mean codice_29 rather than codice_30.
List of Pokémon Adventures characters
His first three Pokémon are Nana (a Poochyena), Kiki (a Skitty), and Rara (a Ralts). He lends Rara to Wally, but due to an earthquake which separates them, he did not get her back until much later on. He also had Feefee (a Feebas), Fofo (a Castform), and Mumu (a Mudkip). In Volume 22, it is revealed that Ruby also owned a Celebi that he came across in Johto.
List of O-Parts Hunter characters
is a treasure hunter who is researching the Legendary O-Part like her father, Zect Crescent. After bumping into Jio, she hires him as her bodyguard and they begin traveling together. Despite being only fifteen, Ruby has extensive knowledge of ancient languages. She smiles almost constantly, saying that after her father died, she realized that crying and running away will not solve anything. She always worries about Jio and Ball, especially when they are fighting against other O.P.T.s. Ruby shares a strong friendship with the two boys, but seems to have more intimate feelings for Jio. She carries a Jade Pendant necklace that her father gave her, which is revealed to be the S rank O-Part with over 100 Effects. Proximity to this Key of Solomon is what awakens an Angel in its host.
Resource acquisition is initialization
Ownership of dynamically allocated objects (memory allocated with new in C++) can also be controlled with RAII, such that the object is released when the RAII (stack-based) object is destroyed. For this purpose, the C++11 standard library defines the smart pointer classes codice_2 for single-owned objects and codice_3 for objects with shared ownership. Similar classes are also available through codice_4 in C++98, and codice_5 in the Boost libraries.
Ruby
A ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum (aluminium oxide). Other varieties of gem-quality corundum are called sapphires. Ruby is one of the traditional cardinal gems, together with amethyst, sapphire, emerald, and diamond. The word "ruby" comes from "ruber", Latin for red. The color of a ruby is due to the element chromium.

Ruby MRI
Matz's Ruby Interpreter or Ruby MRI (also called CRuby) was the reference implementation of the Ruby programming language named after Ruby creator Yukihiro Matsumoto ("Matz"). Until the specification of the Ruby language in 2011, the MRI implementation was considered the "de facto" reference, especially since an independent attempt to create the specification (RubySpec) had failed. Starting with Ruby 1.9, and continuing with Ruby 2.x and above, the official Ruby interpreter has been YARV ("Yet Another Ruby VM").

Resource Description Framework
The subject of an RDF statement is either a uniform resource identifier (URI) or a blank node, both of which denote resources. Resources indicated by blank nodes are called anonymous resources. They are not directly identifiable from the RDF statement. The predicate is a URI which also indicates a resource, representing a relationship. The object is a URI, blank node or a Unicode string literal. 
As of RDF 1.1 resources are identified by IRI's. IRI is a generalization of URI.

In Ruby, classes are never closed: methods can always be added to an existing class. This applies to "all" classes, including the standard, built-in classes. All that is needed to do is open up a class definition for an existing class, and the new contents specified will be added to the existing contents. A simple example of adding a new method to the standard library's codice_38 class:
Apache Buildr
Though Buildr's general philosophy is similar to Maven, it uses Ruby's scripting possibilities to provide a more flexible and customizable programming model. The user writes a Ruby build script, declaring a project, its sub-projects, artifacts, dependencies, packaging rules, etc. Based on these declarations, a list of standard targets are provided to compile or package the project, upload a prepared package to a remote repository, clean up the build results, run tests and so on. Hooks are provided to execute custom Ruby code before or after the standard targets, allowing the user to comfortably override any defaults and further specify the behavior of the standard targets. New, completely user-written targets can be added.
Interactive Ruby Shell
Interactive Ruby Shell (IRB or irb) is a REPL for programming in the object-oriented scripting language Ruby. The abbreviation irb comes from the fact that the filename extension for Ruby is ".rb", although interactive Ruby files do not have an extension of ".irb".
Ruby character
In 2001, the W3C published the Ruby Annotation specification for supplementing XHTML with ruby markup. Ruby markup is not a standard part of HTML 4.01 or any of the XHTML 1.0 specifications (XHTML-1.0-Strict, XHTML-1.0-Transitional, and XHTML-1.0-Frameset), but was incorporated into the XHTML 1.1 specification, and is expected to be a core part of HTML5 once the specification becomes finalised by the W3C.
Anonymous function
Also, a function is an Object instance (likewise objects are Function instances) and the object literal notation brackets, codice_57 for braced code, are used when defining a function this way (as opposed to using codice_58). In a very broad non-rigorous sense (especially since global bindings are compromised), an arbitrary sequence of braced JavaScript statements, codice_59, can be considered to be a fixed point of
Pokémon Ruby and Sapphire
The game is essentially a storage system for the Game Boy Advance "Pokémon" games that allows players to trade and store Pokémon that they have caught in "Ruby", "Sapphire", "Emerald, ""FireRed", and "LeafGreen" onto a GameCube memory card. Players can then organize and interact with their Pokémon on the GameCube, such as allowing them to breed. Unique Pokémon can also be acquired. Another feature allows the games to be played on the television via the GameCube Game Boy Advance Cable. Options such as taking screenshots of the game are available in this mode. Another addition is the "Showcase", where players can create and display game pieces of Pokémon.
Ruby (programming language)
One of the differences from Python and Perl is that Ruby keeps all of its instance variables completely private to the class and only exposes them through accessor methods (codice_11, codice_12, etc.). Unlike the "getter" and "setter" methods of other languages like C++ or Java, accessor methods in Ruby can be created with a single line of code via metaprogramming; however, accessor methods can also be created in the traditional fashion of C++ and Java. As invocation of these methods does not require the use of parentheses, it is trivial to change an instance variable into a full function, without modifying a single line of calling code or having to do any refactoring achieving similar functionality to C# and VB.NET property members.
Comparison of programming languages (associative array)
Ruby also supports many other useful operations on hashes, such as merging hashes, selecting or rejecting elements that meet some criteria, inverting (swapping the keys and values), and flattening a hash into an array.
Physical body
In common usage an object is the material inside the boundary of an object, in 3-dimensional space. The boundary of an object is a contiguous surface which may be used to determine what is inside, and what is outside an object. An object is a single piece of material, whose extent is determined by a description based on the properties of the material. An imaginary sphere of granite within a larger block of granite would not be considered an identifiable object, in common usage. A fossilized scull encased in a rock may be considered an object because it is possible to determine the extent of the scull based on the properties of the material.
Ring (mathematics)
Let "C" be a category with finite products. Let pt denote a terminal object of "C" (an empty product). A ring object in "C" is an object "R" equipped with morphisms formula_261 (addition), formula_262 (multiplication), formula_263 (additive identity), formula_264 (additive inverse), and formula_265 (multiplicative identity) satisfying the usual ring axioms. Equivalently, a ring object is an object "R" equipped with a factorization of its functor of points formula_266 through the category of rings: formula_267.
Ruby (programming language)
In 1999, the first English language mailing list "ruby-talk" began, which signaled a growing interest in the language outside Japan. In this same year, Matsumoto and Keiju Ishitsuka wrote the first book on Ruby, "The Object-oriented Scripting Language Ruby" (オブジェクト指向スクリプト言語 Ruby), which was published in Japan in October 1999. It would be followed in the early 2000s by around 20 books on Ruby published in Japanese.
Ruby MRI
Yukihiro Matsumoto ("Matz") started working on Ruby on February 24, 1993, and released it to the public in 1995. "Ruby" was named as a gemstone because of a joke within Matsumoto's circle of friends alluding to the name of the Perl programming language.
Pokémon Ruby and Sapphire
Like other "Pokémon" games, "Ruby" and "Sapphire"'s gameplay is linear; the main events occur in a fixed order. The protagonist of "Pokémon Ruby" and "Sapphire" is a child who has recently moved to a small town called Littleroot Town. At the beginning of the games, the player chooses either Treecko, Torchic, or Mudkip to protect Professor Birch, the regional professor, from an attacking poochyena. After defending Birch, the player is taken to his lab and receives the chosen Pokémon as his or her starter Pokémon with the choice of Mudkip, Treecko, or Torchic. After that the player encounters May, daughter of Professor Birch. The player's rival, who appears as the professor's child, is also a Pokémon Trainer and occasionally battles the player. The games' two main goals are defeating the eight Gym Leaders, proving oneself worthy of challenging the Elite Four and Champion to become the new Champion and completing the Pokédex by capturing, evolving, and trading to obtain all 202 Pokémon (It is possible to obtain all 386 Pokémon, but this requires trading with "Pokémon FireRed" and "LeafGreen").
Ruby on Rails
Ruby on Rails is separated into various packages, namely ActiveRecord (an object-relational mapping system for database access), Active Resource (provides web services), Action Pack, Active Support and Action Mailer. Prior to version 2.0, Ruby on Rails also included the Action Web Service package that is now replaced by Active Resource. Apart from standard packages, developers can make plugins to extend existing packages. Earlier Rails supported plugins within their own custom framework; version 3.2 deprecates these in favor of standard Ruby "gems".
Resource acquisition is initialization
However, object lifetimes are not necessarily bound to any scope, and objects may be destroyed non-deterministically or not at all. This makes it possible to accidentally leak resources that should have been released at the end of some scope. Objects stored in a static variable (notably a global variable) may not be finalized when the program terminates, so their resources are not released; CPython makes no guarantee of finalizing such objects, for instance. Further, objects with circular references will not be collected by a simple reference counter, and will live indeterminately long; even if collected (by more sophisticated garbage collection), destruction time and destruction order will be non-deterministic. In CPython there is a cycle detector which detects cycles and finalizes the objects in the cycle, though prior to CPython 3.4, cycles are not collected if any object in the cycle has a finalizer.
Common Object Request Broker Architecture
Object references are lightweight objects matching the interface of the real object (remote or local). Method calls on the reference result in subsequent calls to the ORB and blocking on the thread while waiting for a reply, success or failure. The parameters, return data (if any), and exception data are marshaled internally by the ORB according to the local language and OS mapping.
Ruby Thursday
Ruby Thursday's head has been replaced with a mass of "organic circuitry". The red spherical mass can alter its shape so she can form tentacles and fire projectiles and energy blasts. If the sphere is removed from the body, Ruby can still control her body.
Reference
Reference is a relation between objects in which one object designates, or acts as a means by which to connect to or link to, another object. The first object in this relation is said to "refer to" the second object. It is called a "name" for the second object. The second object, the one to which the first object refers, is called the "referent" of the first object. A name is usually a phrase or expression, or some other symbolic representation. Its referent may be anything – a material object, a person, an event, an activity, or an abstract concept.

Object-oriented programming
Objects are the run-time entities in an object-oriented system. They may represent a person, a place, a bank account, a table of data, or any item that the program has to handle.
Ruby (programming language)
Ruby is a dynamic, interpreted,
reflective, object-oriented, general-purpose programming language. It was designed and developed in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan.
Binary large object
A Binary Large OBject (BLOB) is a collection of binary data stored as a single entity in a database management system. Blobs are typically images, audio or other multimedia objects, though sometimes binary executable code is stored as a blob. Database support for blobs is not universal.
Local variable
Ruby as a language was inspired also by Perl, but in this case, the notation was made simpler: a global variable name must be preceded by a $ sign, like codice_13, while a local variable has simply no $ sign in front of its name, like codice_14 (while in perl all scalar values have a $ in front). Note that Ruby only provides built-in support for statically-scoped local variables like Perl's codice_4, not dynamically-scoped local variables like Perl's codice_3. There is at least one library for Ruby that provides dynamically-scoped variables.
LPC (programming language)
Each object has variables (attributes) and functions (methods). The variables store the object's state; the functions are executable routines that can be called in the object. An object is uniquely defined by the name of the file in which it comes from, plus, if a clone, a numeric identifier. In a typical implementation, a clone of the file codice_1 which is the third clone created in the current run session will be codice_2. The blueprint object corresponding to codice_1 is simply codice_4. In a MUD game, common objects include rooms, weapons, armor, and non-player character (NPCs). Most mudlibs define inheritable objects for such common things. In the LPMud 2.4.5 mudlib, for example, the parent object for all rooms is codice_5.

The COM permits interprocess communication (such as between Ruby and Internet Explorer) and dynamic object creation and manipulation (which is what the Ruby program does to the Internet Explorer). Microsoft calls this OLE automation, and calls the manipulating program an automation controller. Technically, the Internet Explorer process is the server and serves the automation objects, exposing their methods; while the Ruby program then becomes the client which manipulates the automation objects.
Yubi lakpi
Unlike rugby it is an individual sport, not a team one. Before the start of the game, players rub their bodies with mustard oil and water to make slippery to catch each other. A coconut properly soaked with oil is place in front of the chief guest of the function, known as the "King", who does not take part in the game itself. Before the start the coconut is placed in front of the seat of the "King".
Other features of the game include:Each side has 7 players in a field that is about 45 x 18 metres in area. One end of the field has a rectangular box 4.5 x 3 metres. One side of which forms the central portion of the goal line. To score a goal a player has to approach the goal from the front with his oiled coconut and pass the goal line. The coconut serves the purpose of a ball and is offered to the king or the judges who sit just beyond the goal line. However, in ancient times the teams were not equally matched but the players, with the coconut had to tackle all the rest of the players.
Constant (computer programming)
One enforced convention is that in Ruby, any variable that begins with a capital letter is considered a constant, including class names.
Nu (programming language)
The example is a basic definition of a complex number: it defines the instance variables, and a method to initialize the object. It shows the similarity between the code in Nu and the equivalent in Objective-C; it also shows the similarity with Ruby.
ERuby
The second code snippet changes to the below code:
string = "The value of x is: #{x}"
x = 400
puts string
The above code will not get executed. This is because the 1st line does not know the value of x when it gets executed. Thus, the main reason of using an ERB object is to write templates ahead of time, by "binding" variables and methods which may not exist at the given time. The template gets processed only when "result" is called on the ERB object. In order to get access to instance methods and instance variable of an object, ERB makes use of a "binding" object. Access to variables and methods of an object is given by the private "binding" object which exists in each ruby class. It is easy to get access to methods and variables within the method of a class. But to access variables of a different class, that class will have to expose its binding object via a public method. The example is as shown below:
class ERBExample
Rubychem
RubyChem (pronounced /ˈruːˈbeːˈkːˈem/) is a freely available (MIT License) program, written in Ruby, supporting the calculation of moles, balancing chemical equations and valence orbital calculations.
Ellipsis (computer programming)
In Ruby the codice_2 operator denotes a half-open range, i.e. that includes the start value but not the end value.
Scope resolution operator
In some languages, notably those influenced by Modula-3, including Python and Go, modules are objects, and scope resolution within modules is a special case of usual object member access, so the usual method operator codice_1 is used for scope resolution. Other languages, notably C++ and Ruby, feature both scope resolution and method access, which interact in various ways; see examples below.
?:
Example of using this operator in Ruby:
Returns "false value".
Mathematical object
In mathematical practice, an "object" is anything that has been (or could be) formally defined, and with which one may do deductive reasoning and mathematical proofs. Commonly encountered mathematical objects include numbers, permutations, partitions, matrices, sets, functions, and relations. Geometry as a branch of mathematics has such objects as hexagons, points, lines, triangles, circles, spheres, polyhedra, topological spaces and manifolds. Another branch—algebra—has groups, rings, fields, group-theoretic lattices, and order-theoretic lattices. Categories are simultaneously homes to mathematical objects and mathematical objects in their own right. In proof theory, proofs and theorems are also mathematical objects.

Ruby 1.8 has been the subject of several industry standards. The language specifications for Ruby were developed by the Open Standards Promotion Center of the Information-Technology Promotion Agency (a Japanese government agency) for submission to the Japanese Industrial Standards Committee (JISC) and then to the International Organization for Standardization (ISO). It was accepted as a Japanese Industrial Standard (JIS X 3017) in 2011 and an international standard (ISO/IEC 30170) in 2012.
Ruby (programming language)
Ruby 2.2.0 was released on Christmas Day in 2014. The release includes speed-ups, bugfixes, and library updates and removes some deprecated APIs. Most notably, Ruby 2.2.0 introduces changes to memory handling an incremental garbage collector, support for garbage collection of symbols and the option to compile directly against jemalloc. It also contains experimental support for using vfork(2) with system() and spawn(), and added support for the Unicode 7.0 specification.
List of Pokémon Adventures characters
It is revealed in Volume 21 that Ruby likes Sapphire and she was the girl who Ruby had rescued, though neither of them recognized the other when they met at the beginning of the arc. Ruby realizes her identity when she reminisces the event, and reveals his identity to her by showing her a scar on his forehead, which he sustained while holding off a wild Salamence.
Ruby (programming language)
The maturity of Ruby implementations tends to be measured by their ability to run the [[Ruby on Rails]] (Rails) framework, because it is complex to implement and uses many Ruby-specific features. The point when a particular implementation achieves this goal is called "the Rails singularity". The reference implementation [[Ruby MRI|(MRI)]], [[JRuby]], and [[Rubinius]] are all able to run Rails unmodified in a production environment.
Ruby (programming language)
codice_26 is a constant and is a reference to a codice_37 object.
Inform
The Inform programming language is object-oriented and procedural. A key element of the language is objects. Objects are maintained in an object tree which lists the parent–child relationships between objects. Since the parent–child relationship is often used to represent location, an object which is the parent of another object is often said to "hold" it. Objects can be moved throughout the tree. Typically, top level objects represent rooms and other locations within the game, which may hold objects representing the room's contents, be they physical items, non-player characters, the player's character, or background effects. All objects can hold other objects, so a codice_1 object might hold an codice_2 object which is holding a codice_3 object which contains the codice_4 object.

Object-oriented programming
In prototype-based languages the "objects" are the primary entities. No "classes" even exist. The "prototype" of an object is just another object to which the object is linked. Every object has one "prototype" link (and only one). New objects can be created based on already existing objects chosen as their prototype. You may call two different objects "apple" and "orange" a fruit, if the object "fruit" exists, and both "apple" and "orange" have "fruit" as their prototype. The idea of the "fruit" class doesn't exist explicitly, but as the equivalence class of the objects sharing the same prototype. The attributes and methods of the "prototype" are delegated to all the objects of the equivalence class defined by this prototype. The attributes and methods "owned" individually by the object may not be shared by other objects of the same equivalence class; e.g. the attributes "sugar content" may be unexpectedly not present in "apple". Only single inheritance can be implemented through the prototype.
Single Table Inheritance
Single table inheritance is a way to emulate object-oriented inheritance in a relational database. When mapping from a database table to an object in an object-oriented language, a field in the database identifies what class in the hierarchy the object belongs to. All fields of all the classes are stored in the same table, hence the name "Single Table Inheritance". In Ruby on Rails the field in the table called 'type' identifies the name of the class. In Hibernate (Java) and Entity Framework this pattern is called Table-Per-Class-Hierarchy and Table-Per-Hierarchy (TPH) respectively., and the column containing the class name is called the Discriminator column.
Symbol (programming)
The following is a simple example of a symbol literal in Ruby:
Object (computer science)
Rather than structure programs as code and data, an object-oriented system integrates the two using the concept of an "object". An object has state (data) and behavior (code). Objects can correspond to things found in the real world. So for example, a graphics program will have objects such as "circle", "square", "menu". An online shopping system will have objects such as "shopping cart, customer, product". The shopping system will support behaviors such as "place order", "make payment", and "offer discount". The objects are designed as class hierarchies. So for example with the shopping system there might be high level classes such as "electronics product", "kitchen product", and "book". There may be further refinements for example under "electronic products": "CD Player, DVD player", etc. These classes and subclasses correspond to sets and subsets in mathematical logic.
Subject-oriented business process management
In many natural languages, subject, predicate and object are the basic building blocks of a sentence. The subject of a sentence is the person, place, thing, or idea that is carrying out the action denoted by the predicate. A predicate has at its center a simple predicate, which is always the verb or verbs linked to the subject. The direct object is the person or thing that receives the action of the verb. It normally follows the verb. The indirect object is the person or thing to whom or to which the action was directed or for whom or for which the action was performed. The indirect object is in a way the recipient of the direct object.
