public class InputMap extends Object implements Serializable
InputMap provides a binding between an input event (currently only
KeyStrokes are used) and an
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
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.
InputMap with no parent and no mappings.
public void setParent(InputMap map)
InputMapthat is the parent of this one
public InputMap getParent()
InputMapthat is the parent of this one, or null if this
InputMaphas no parent
public void put(KeyStroke keyStroke, Object actionMapKey)
Adds a binding for
actionMapKey is null, this removes the current binding for
public Object get(KeyStroke keyStroke)
Returns the binding for
keyStroke, messaging the parent
InputMap if the binding is not locally defined.
public void remove(KeyStroke key)
Removes the binding for
key from this
public void clear()
Removes all the mappings from this
public KeyStroke keys()
KeyStrokes that are bound in this
public int size()
Returns the number of
public KeyStroke allKeys()
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.
