    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 its AccessibleContext (see `Accessible`) and then calling the `AccessibleContext.getAccessibleAction()` method. If the return value is not null, the object supports this interface.

  `Accessible`, `Accessible.getAccessibleContext()`, `AccessibleContext`, `AccessibleContext.getAccessibleAction()`

Field Summary
`static String` | `DECREMENT` An action which decrements a value.
`static String` | `INCREMENT` An action which increments a value.
`static String` | `TOGGLE_EXPAND` An action which causes a tree node to collapse if expanded and expand if collapsed.

Method Summary
`boolean` | `doAccessibleAction(int i)` Performs the specified Action on the object
`int` | `getAccessibleActionCount()` Returns the number of accessible actions available in this object If there are more than one, the first one is considered the "default" action of the object.
`String` | `getAccessibleActionDescription(int i)` Returns a description of the specified action of the object.
