java.lang.Objectorg.apache.commons.collections.ProxyMap
public abstract class ProxyMap
This Map wraps another Map
implementation, using the wrapped instance for its default
implementation. This class is used as a framework on which to
build to extensions for its wrapped Map object which
would be unavailable or inconvenient via sub-classing (but usable
via composition).
This implementation does not perform any special processing with
entrySet(), keySet() or values(). Instead
it simply returns the set/collection from the wrapped map. This may be
undesirable, for example if you are trying to write a validating
implementation it would provide a loophole around the validation. But,
you might want that loophole, so this class is kept simple.
