java.lang.Object | +--org.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).
An example use case is where the wrapped Map
needs
synchronization (to make it thread-safe), but the Map
returned by Collections.synchronizedMap(map)
hides part of map
's public interface.
