Class FullMap

java.lang.Object
  nu.staldal.lsp.FullMap

All Implemented Interfaces:

java.util.Map<java.lang.String,java.lang.Object>

public class FullMap
extends java.lang.Object
implements java.util.Map<java.lang.String,java.lang.Object>

A special implementation of Map which pretends to have all possible keys. The get(java.lang.Object) method return Void.TYPE for all keys. The containsKey(java.lang.Object) method return true for all keys. All other methods throws UnsupportedOperationException.

Implements the Singleton pattern.
