javax.swing.ActionMap

ActionMap

Java SE 6

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.

Methods

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 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.
