virtual void OnBeginCollection ( )

pure virtual

Called at the beginning of an iteration.

OnBeginThread()

virtual void OnBeginThread ( const TraceThreadId &  threadId )

pure virtual

Called before the first event of from the thread with threadId is encountered.

OnEndCollection()

virtual void OnEndCollection ( )

pure virtual

Called at the end of an iteration.

OnEndThread()

virtual void OnEndThread ( const TraceThreadId &  threadId )

pure virtual

Called after the last event of from the thread with threadId is encountered.

OnEvent()

virtual void OnEvent ( const TraceThreadId &  threadId, const TfToken &  key, const TraceEvent &  event  )

pure virtual

Called for every event event with key on thread threadId if AcceptsCategory returns true.
