Class MapContext<K,​V>

  • All Implemented Interfaces:
    java.util.Map<K,​V>, LocalizedMap<V>
    Direct Known Subclasses:
    MapStack, MultivaluedMapContext
    public class MapContext<K,​V>
extends java.lang.Object
implements java.util.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.

      Modifier and Type Method Description
      void addToBottom​(java.util.Map<K,​V> existingMap)
      Puts an existing Map on the BOTTOM of the stack (bottom meaning will be overriden by lower layers on the stack, ie everything else already there)

      java.util.Set<K> keySet()  
      java.util.Map<K,​V> pop()
      Remove and returns the Map from the top of the stack; if there is only one Map on the stack it returns null and does not remove it
