java.lang.Objectorg.apache.commons.collections.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.

public ProxyMap(Map map)
Note that the map is used for delegation, and is not copied. This is
different to the normal use of a Map parameter in
collections constructors.
