Class DelegateMap

java.lang.Object
  orbital.util.DelegateMap

All Implemented Interfaces:

java.io.Serializable, java.util.Map

Direct Known Subclasses:

InterpretationBase

public class DelegateMap
extends java.lang.Object
implements java.util.Map, java.io.Serializable

A DelegateMap that works as a delegator to maps. It implements the java.util.Map interface itself, and so a DelegateMap is a Map delegating to a specified implementation Map.
