readPileUp()

template<typename T >

void edm::PileUp::readPileUp	(	edm::EventID const &	signal,
		std::vector< edm::SecondaryEventIDAndFileInfo > &	ids,
		T	eventOperator,
		int const	pileEventCnt,
		StreamID const &	streamID
	)

Generates events from a VectorInputSource. This function decides which method of VectorInputSource to call: sequential, random, or pre-specified. The ids are either ids to read or ids to store while reading. eventOperator has a type that matches the eventOperator in VectorInputSource::loopRandom.

The "signal" event is optionally used to restrict the secondary events used for pileup and mixing.
