| Returns ClassPathImplementation representing the content of the PathResourceImplementation.
If the PathResourceImplementation represents leaf resource, it returns null.
The ClassPathImplementation is live and can be used for path resource content
modification.
Semi-deprecated. There was never a real reason for this method to exist.
If implementing PathResourceImplementation you can simply return null;
it is unlikely anyone will call this method anyway.
