Disabled: no SafeJ information.

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);

Constructor Detail

ActionMap

public ActionMap()
Class is disabled.

Creates an ActionMap with no parent and no mappings.

Method Detail

setParent

public void setParent(ActionMap map)
Class is disabled.

Sets this ActionMap's parent.

Parameters:
map - the ActionMap that is the parent of this one

getParent

public ActionMap getParent()
Class is disabled.

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)
Class is disabled.

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)
Class is disabled.

Returns the binding for key, messaging the parent ActionMap if the binding is not locally defined.


remove

public void remove(Object key)
Class is disabled.

Removes the binding for key from this ActionMap.


clear

public void clear()
Class is disabled.

Removes all the mappings from this ActionMap.


keys

public Object[] keys()
Class is disabled.

Returns the Action names that are bound in this ActionMap.


size

public int size()
Class is disabled.

Returns the number of bindings in this ActionMap.

Returns:
the number of bindings in this ActionMap

allKeys

public Object[] allKeys()
Class is disabled.

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.
