public class: ActionMap [javadoc | source]
java.lang.Object
   javax.swing.ActionMap

All Implemented Interfaces:
    java$io$Serializable

Direct Known Subclasses:
    KeymapActionMap, LazyActionMap, ActionMapUIResource

ActionMap provides mappings from Objects (called keys or Action names) to Actions. An ActionMap is usually used with an InputMap to locate a particular action when a key is pressed. As with InputMap, an ActionMap can have a parent that is searched for keys not defined in the ActionMap.

As with InputMap if you create a cycle, eg:

  ActionMap am = new ActionMap();
  ActionMap bm = new ActionMap():
  am.setParent(bm);
  bm.setParent(am);
some of the methods will cause a StackOverflowError to be thrown.
Constructor:
 public ActionMap() 
Method from javax.swing.ActionMap Summary:
allKeys,   clear,   get,   getParent,   keys,   put,   remove,   setParent,   size
Methods from java.lang.Object:
clone,   equals,   finalize,   getClass,   hashCode,   notify,   notifyAll,   toString,   wait,   wait,   wait
Method from javax.swing.ActionMap Detail:
 public Object[] allKeys() 
    Returns an array of the keys defined in this ActionMap and its parent. This method differs from keys() in that this method includes the keys defined in the parent.
 public  void clear() 
    Removes all the mappings from this ActionMap.
 public Action get(Object key) 
    Returns the binding for key, messaging the parent ActionMap if the binding is not locally defined.
 public ActionMap getParent() 
    Returns this ActionMap's parent.
 public Object[] keys() 
    Returns the Action names that are bound in this ActionMap.
 public  void put(Object key,
    Action action) 
    Adds a binding for key to action. If action is null, this removes the current binding for key.

    In most instances, key will be action.getValue(NAME).

 public  void remove(Object key) 
    Removes the binding for key from this ActionMap.
 public  void setParent(ActionMap map) 
    Sets this ActionMap's parent.
 public int size() 
    Returns the number of bindings in this {@code ActionMap}.
