void ProcessingController::setTransitionToEvent

(

edm::EventID const &

iID

)

Tells the framework that the next event to processes should be iID. If event iID can not be found in the source, the job will drop out of the event loop.

void ProcessingController::setTransitionToNextEvent

(

)

Tells the framework that we should go onto the next event in the sequence. If there is no next event the job will drop out of the event loop.
