public class ActionManager
The application's ActionManager
provides read-only cached
access to ActionMaps
that contain one entry for each method
marked with the @Action
annotation in a class.

protected final ApplicationContext getContext()
public ApplicationActionMap getActionMap()
ActionMap
chain for the entire Application
.
Returns an ActionMap
with the @Actions
defined
in the application's Application
subclass, i.e. the
the value of:
ApplicationContext.getInstance().getApplicationClass()The remainder of the chain contains one
ActionMap
for each superclass, up to Application.class
. The
ActionMap.get()
method searches the entire chain, so
logically, the ActionMap
that this method returns contains
all of the application-global actions.
The value returned by this method is cached.

public ApplicationActionMap getActionMap(java.lang.Class actionsClass, java.lang.Object actionsObject)
ApplicationActionMap
chain for the specified
actions class and target object.
The specified class can contain methods marked with
the @Action
annotation. Each one will be turned
into an ApplicationAction
object
and all of them will be added to a single
ApplicationActionMap
. All of the
ApplicationActions
invoke their actionPerformed
method on the specified actionsObject
.
The parent of the returned ActionMap
is the global
ActionMap
that contains the @Actions
defined
in this application's Application
subclass.
To bind an @Action
to a Swing component, one specifies
the @Action's
name in an expression like this:
ApplicationContext ctx = Application.getInstance(MyApplication.class).getContext(); MyActions myActions = new MyActions(); myComponent.setAction(ac.getActionMap(myActions).get("myAction"));
The value returned by this method is cached. The lifetime of
the cached entry will be the same as the lifetime of the actionsObject
and the ApplicationActionMap
and ApplicationActions
that refer to it. In other words, if you
drop all references to the actionsObject
, including
its ApplicationActions
and their ApplicationActionMaps
, then the cached ActionMap
entry
will be cleared.
