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.

  • Method Details

    • getContexts

      public Deque<Map<K,V>> getContexts()
      Gets contexts.
      Returns:
      the contexts
    • push

      public void push()
      Puts a new Map on the top of the stack
    • push

      public void push(Map<K,V> existingMap)
      Puts an existing Map on the top of the stack (top meaning will override lower layers on the stack)
    • addToBottom

      public void addToBottom(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)
    • pop

      public 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
