Class CompositeMap<K,V>

java.lang.Object

net.mdatools.modelant.core.util.map.CompositeMap<K,V>

All Implemented Interfaces:

Map<K,V>

public class CompositeMap<K,V>
extends Object
implements Map<K,V>

This class is a composite Map implementation, so that when creating a new map form another, this implementation does not copy the original, but any access is delegated to the wrapped one.
