Class WrappedMap

java.lang.Object
  extended by helma.util.WrappedMap
All Implemented Interfaces:
java.util.Map
Direct Known Subclasses:
CopyOnWriteMap

public class WrappedMap
extends java.lang.Object
implements java.util.Map

A Map that wraps another map. We use this class to be able to wrap maps as native objects within a scripting engine rather than exposing them through Java reflection. Additionally, instances of this class can be set to readonly so that the original map can't be modified.
