Detailed Description

Runs PYTHIA 6 and builds an output tree file in the ROOT environment.

The output tree is populated with EventPythia objects. PYTHIA options (including initialisation) should be provided via the ROOT interface class TPythia6 before running the tree-building.

Constructor & Destructor Documentation

Pythia6()

erhic::Pythia6::Pythia6	(	TFile *	file,
		VirtualEventFactory *	factory,
		int	nEvents,
		const std::string &	treeName = "EICTree",
		const std::string &	branchName = "event",
		int	printInterval = 1000
	)

Constructor.

Associates the output of this PYTHIA run with a file. Generate events using the provided event factory. Both the file and the factory should be dynamically allocated. Pythia6 takes ownership and deletes them. Define the number of events to produce, and optionally provide a tree and branch name.

Destructor.

Member Function Documentation

Run()

bool erhic::Pythia6::Run ( )

virtual

Runs PYTHIA and writes output.

Todo:

Implement selection of correct event factory (either erhic::Pythia6EventBuilder or hadronic::Pythia6EventFactory) depending on requested beam types.
