Detailed Description

JoinEvents processor allows join events (based on the run number and event number) from a different file.

All collections in the event are added to the current event, provided their collection name does not yet exist in the event. If the collection names are the same the user can optionally specify a post fix that is added to all collection names from the joined event in order to avoid name clashes.
