Detailed Description

ForwardReplayTask will perform a forward replay using PEARL_forward_replay() when executed. To use this class, derive a class from ForwardReplayTask and add some callback methods.

Example:

 class MyReplay : public ForwardReplayTask {
   public:
     MyReplay(const GlobalDefs& defs, LocalTrace& trace) 
       : ForwardReplayTask(defs, trace) 
     {
       register_callback(MPI_SEND, &MyReplay::cb_send);
     }

   private:
     void cb_send(const CallbackManager& cbmanager, int user_event,
                  const Event& event, CallbackData* cdata)
     {
       // ...
     }
 };

Constructor & Destructor Documentation

ForwardReplayTask	(	const GlobalDefs &	defs,
		LocalTrace &	trace,
		CallbackData *	cbdata = 0,
		CallbackManager *	cbmanager = 0
	)			[protected]

Constructor. Initializes internal data.

The constructor creates a default callback manager of type pearl::CallbackManager. You can specify a different callback manager by passing a non-null pointer to a callback manager object via the cbmanager argument. Note that ForwardReplayTask takes ownership of the callback manager object, i.e., it will be freed automatically in the ForwardReplayTask destructor.

Parameters:

	defs	Reference to global definition object
	trace	Reference to the trace object the replay will be performed on
	cbdata	Pointer to callback data object to be passed to the callback functions (default 0)
	cbmanager	Pointer to callback manager object (default 0)

Member Function Documentation

bool replay

(

)

[protected, virtual]

Executes a forward replay, i.e., iterates over the events of the associated trace from the beginning to the end and executes the corresponding callbacks registered with the callback manager.

Returns:

Always true

Implements ReplayTask.
