All Implemented Interfaces:

Map<K,V>, LocalizedMap<V>

Direct Known Subclasses:

MapStack, MultivaluedMapContext

public class MapContext<K,V>
extends Object
implements Map<K,V>, LocalizedMap<V>

Map Context Provide a combined view for a collection of maps which are organized in a deque. All write operations affect only the head of the deque.
