Defines a Pointcut for any constructor to a class implementing Validatable.
The Pointcut will return {@code true} for all non-default Constructors, i.e. when the signature
of the JoinPoint has more than 0 arguments.

@param joinPoint The currently executing joinPoint.
Defines a Pointcut for any constructor to a class implementing Validatable . The Pointcut will return { @code true } for all non - default Constructors i . e . when the signature of the JoinPoint has more than 0 arguments .
