public interface AccessibleAction

The AccessibleAction interface should be supported by any object that can perform one or more actions. This interface provides the standard mechanism for an assistive technology to determine what those actions are as well as tell the object to perform them. Any object that can be manipulated should support this interface. Applications can determine if an object supports the AccessibleAction interface by first obtaining itsAccessibleContext (see Accessible) and then calling theAccessibleContext.getAccessibleAction() method. If the return value is not null, the object supports this interface.
