The LesHouchesEventHandler inherits from the general EventHandler class and administers the reading of events generated by external matrix element generator programs according to the Les Houches accord.
The class has a list of LesHouchesReader
s which typically are connected to files with event data produced by external matrix element generator programs. When an event is requested by LesHouchesEventHandler, one of the readers are chosen, an event is read in and then passed to the different StepHandler
defined in the underlying EventHandler class.
