| Interface defining 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 has been introduced and removed from PonderUtilCore a number
of times under the name "ObjectGetter" - on every occasion before now
it has been determined that its use represented some kind of design error.
The only current use is in
BeanExploder so that it may receive
inner bean definitions delivered via RSAC, resulting in a more concise
Spring definition. This interface is defined here in PUC to avoid a dependence
at this level on Spring.
