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.
