Member Function Documentation

void fawkes::openni::HandIfObserver::bb_interface_created ( const char *  type, const char *  id  ) throw ()

virtual

BlackBoard interface created notification.

This is called whenever an interface is created for a type that you registered for.

Parameters:

type	type of the interface. If you want to store this make a copy as it is not guaranteed that the supplied string exists for longer than the duration of the method call
id	ID of the newly created interface. If you want to store this make a copy as it is not guaranteed that the supplied string exists for longer than the duration of the method call

Reimplemented from fawkes::BlackBoardInterfaceObserver.

void fawkes::openni::HandIfObserver::process_queue

(

)

Process internal queue.

This should be called regularly to process incoming events.
