Description

Interface class for Grabba device button press and release events.

Objects which implement this interface may receive callbacks when these events occur, via delegation from a ButtonListener object.

Note that this interface need not be directly implemented; it may be simpler to subclass ButtonListener and thereby receive the events directly.

Thread safety: This interface is intended to be thread-safe; any classes deriving from it should ensure that the relevant methods are callable from any thread.

See also: ButtonAPI for related API functions, and ButtonListener for more detailed descriptions of each event.
