/**
* Defines a factory which can return an Object instance
* (possibly shared or independent) when invoked.
*
* This interface is typically used to encapsulate a generic factory which
* returns a new instance (prototype) of some target object on each invocation.
*
*
This interface is similar to FactoryBean, but implementations of the latter
* are normally meant to be defined as instances by the user in a BeanFactory,
* while implementations of this class are normally meant to be fed as a property
* to other beans. As such, the getObject method has different
* exception handling behavior.
