Detailed Description

HDF5 version 2 file reader. Converts to Pythia-internal events by acting as replacement Les Houches Event reader.

Constructor & Destructor Documentation

LHAupH5v2	(	HighFive::File *	h5fileIn,
		size_t	firstEventIn,
		size_t	readSizeIn,
		bool	normalize
	)

inline

Read event-file header and events.

This reads the init information.

Member Function Documentation

bool setEvent ( int idProc = 0 )

overridevirtual

Read an event.

Equivalent of end of file.

Read event.

Skip zero-weight events (empty), but add trials.

Events with zero weight are empty.

Communicate event weight to Info.

Set particles.

Scale setting

Update counters.

Implements LHAup.

bool setInit ( )

inlineoverridevirtual

A pure virtual method setInit, wherein all initialization information is supposed to be set in the derived class. Can do this by reading a file or some other way, as desired. Returns false if it did not work.

Implements LHAup.
