/**
* The {@code 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 {@code AccessibleAction} interface by first obtaining its
* {@code AccessibleContext} (see {@link Accessible}) and then calling the
* {@link AccessibleContext#getAccessibleAction} method. If the return value is
* not {@code null}, the object supports this interface.
