InputMap JDK 1.6)

Description

public class InputMap

InputMap provides a binding between an input event (currently only KeyStrokes are used) and an Object.

InputMap provides a binding between an input event (currently only KeyStrokes are used) and an Object. InputMaps are usually used with an ActionMap, to determine an Action to perform when a key is pressed. An InputMap can have a parent that is searched for bindings not defined in the InputMap.

As with ActionMap if you create a cycle, eg:

   InputMap am = new InputMap();
   InputMap bm = new InputMap():
   am.setParent(bm);
   bm.setParent(am);

some of the methods will cause a StackOverflowError to be thrown.

public KeyStroke allKeys ()

Returns an array of the KeyStrokes defined in this InputMap and its parent.

Returns an array of the KeyStrokes defined in this
InputMap and its parent. This differs from keys() in that
this method includes the keys defined in the parent.

public void clear ()

Removes all the mappings from this InputMap.

public Object get (KeyStroke keyStroke)

Returns the binding for keyStroke, messaging the parent InputMap if the binding is not locally defined.

public InputMap getParent ()

Gets this InputMap's parent.

Gets this InputMap's parent.
Returns: map the InputMap that is the parent of this one, or null if this InputMap has no parent

public KeyStroke keys ()

Returns the KeyStrokes that are bound in this InputMap.

public void put (KeyStroke keyStroke, Object actionMapKey)

Adds a binding for keyStroke to actionMapKey.

Adds a binding for keyStroke to actionMapKey.
If actionMapKey is null, this removes the current binding
for keyStroke.

public void remove (KeyStroke key)

Removes the binding for key from this InputMap.

public void setParent (InputMap map)

Sets this InputMap's parent.

Sets this InputMap's parent.
Parameters:
- map - the InputMap that is the parent of this one

public int size ()

Returns the number of KeyStroke bindings.
