class:ActionMap [NONE]

  • 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);

constructor:ActionMap() [NONE]

  • ActionMap

    public ActionMap()
    Creates an ActionMap with no parent and no mappings.

method:setParent(javax.swing.ActionMap) [NONE]

  • setParent

    public void setParent​(ActionMap map)
    Sets this ActionMap's parent.
    Parameters:
    map - the ActionMap that is the parent of this one

method:getParent() [NONE]

  • 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

method:put(java.lang.Object,javax.swing.Action) [NONE]

  • 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).

    Parameters:
    key - a key
    action - a binding for key

method:get(java.lang.Object) [NONE]

  • get

    public Action get​(Object key)
    Returns the binding for key, messaging the parent ActionMap if the binding is not locally defined.
    Parameters:
    key - a key
    Returns:
    the binding for key

method:remove(java.lang.Object) [NONE]

  • remove

    public void remove​(Object key)
    Removes the binding for key from this ActionMap.
    Parameters:
    key - a key

method:clear() [NONE]

  • clear

    public void clear()
    Removes all the mappings from this ActionMap.

method:keys() [NONE]

  • keys

    public Object[] keys()
    Returns the Action names that are bound in this ActionMap.
    Returns:
    an array of the keys

method:size() [NONE]

  • size

    public int size()
    Returns the number of bindings in this ActionMap.
    Returns:
    the number of bindings in this ActionMap

method:allKeys() [NONE]

  • 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.
    Returns:
