Class MapOfMaps<K1,K2,V>

java.lang.Object
  ca.infoway.messagebuilder.j5goodies.MapOfMaps<K1,K2,V>

Type Parameters:

K1 - - the type of the outer map key.

K2 - - the type of the inner map key.

V - - the type of the map value.

All Implemented Interfaces:

Map<K1,Map<K2,V>>

public class MapOfMaps<K1,K2,V>
extends Object
implements Map<K1,Map<K2,V>>

This class provides simple semantics for the common situation where you want to have a map that contains other maps.
