an object of this class interfaces with an object of the job producer class 210 to produce jobs and job contexts on a continuous feed basis exemplary code for a simple job feed producer 212 implementation returning a list of integers is illustrated in fig1 a 14 f fig1 is an exemplary embodiment of job producer feed manager class 214 objects of this type manage production of the continuous job feed in particular job producer feed manager 214 manages the life cycle of a one depth buffer of jobs the configuration source of deployer 108 may describe buffer minimum and maximum size the frequency to refresh the buffer and other parameters to efficiently manage the continuous job feed a resource is typically a reusable component that may mediate access to physical e g com port or logical e g jdbc connection resources according to framework 100 a resource has the following characteristics a resource can be created given some resource specific context information is capable of timing out if appropriate for the type of resource being used can be considered available or unavailable can refresh itself to prevent being permanently unavailable i e a rogue resource and has the effect of propagating events when refreshed a resource manager such as job dispatcher 110 in fig1 has the following characteristics job dispatcher 110 manages the resource pool in a thread safe and load balanced manner handles addition and removal of resources from the pool handles event propagation due to changes in the resource pool and handles any resource changes.
