ActionMap (Java Platform SE 7 b138)

java.lang.Object
- javax.swing.ActionMap

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

ActionMapUIResource
```
public class ActionMap
extends Object
implements Serializable
```
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.

Method Summary

Methods
Modifier and Type	Method and Description
`Object[]`	`allKeys()` Returns an array of the keys defined in this `ActionMap` and its parent.
`void`	`clear()` Removes all the mappings from this `ActionMap`.
`Action`	`get(Object key)` Returns the binding for `key`, messaging the parent `ActionMap` if the binding is not locally defined.
`ActionMap`	`getParent()` Returns this `ActionMap`'s parent.
`Object[]`	`keys()` Returns the `Action` names that are bound in this `ActionMap`.
`void`	`put(Object key, Action action)` Adds a binding for `key` to `action`.
`void`	`remove(Object key)` Removes the binding for `key` from this `ActionMap`.
`void`	`setParent(ActionMap map)` Sets this `ActionMap`'s parent.
`int`	`size()` Returns the number of bindings in this `ActionMap`.

- Constructor Detail
  - ActionMap
```
public ActionMap()
```
    Creates an ActionMap with no parent and no mappings.
- Method Detail
  - setParent
```
public void setParent(ActionMap map)
```
    Sets this ActionMap's parent.
    
    Parameters:
    map - the ActionMap that is the parent of this one
  - getParent
```
public ActionMap getParent()
```
    Returns this ActionMap's parent.
    
    Returns:
    the ActionMap that is the parent of this one, or null if this ActionMap has no parent
  - put
```
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).
  - get
```
public Action get(Object key)
```
    Returns the binding for key, messaging the parent ActionMap if the binding is not locally defined.
  - remove
```
public void remove(Object key)
```
    Removes the binding for key from this ActionMap.
  - clear
```
public void clear()
```
    Removes all the mappings from this ActionMap.
  - keys
```
public Object[] keys()
```
    Returns the Action names that are bound in this ActionMap.
  - size
```
public int size()
```
    Returns the number of bindings in this ActionMap.
    
    Returns:
    the number of bindings in this ActionMap
  - allKeys
```
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.
