Detailed Description

Interface to PYTHIA 6. Builds EventPythia objects directly from PYTHIA output, without an intermediate text file. Configure PYTHIA options via the ROOT::TPythia6 class.

Remarks
The following fields in EventPythia are not set: F1, F2, R, sigma_rad, SigRadCor, EBrems

Constructor & Destructor Documentation

erhic::Pythia6EventBuilder::Pythia6EventBuilder ( EventMCFilterABC *  filter = NULL)
explicit

Constructor. If a filter is provided, it will be applied so that all events yielded by Create() pass the filter. The filter should be allocated via new and is subsequently owned and deleted by the Pythia6EventBuilder.

erhic::Pythia6EventBuilder::~Pythia6EventBuilder ( )
virtual

Member Function Documentation

TBranch * erhic::Pythia6EventBuilder::Branch ( TTree &  ,
const std::string &   
)
virtual

Add a branch named "name" for the event type generated by this factory to a ROOT TTree. Returns a pointer to the branch, or NULL in the case of an error.

Reimplemented from erhic::VirtualEventFactory.

Definition at line 161 of file Pythia6EventBuilder.cxx.

EventPythia * erhic::Pythia6EventBuilder::Create ( )
virtual

Generates an event from the current state of ROOT::TPythia6. The returned event is dynamically allocated and must be deleted by the user.

Implements erhic::VirtualEventFactory.

Definition at line 45 of file Pythia6EventBuilder.cxx.

std::string erhic::Pythia6EventBuilder::EventName ( ) const
virtual

Returns a string with the full (including namespace) class name of the event type produced. This is important for use with ROOT TTree to ensure the correct event type in branches.

Implements erhic::VirtualEventFactory.

Definition at line 157 of file Pythia6EventBuilder.cxx.

void erhic::Pythia6EventBuilder::Fill ( TBranch &  )
virtual

Calls Create() to generate an event and fills the provided branch with that event. Resets the branch address in doing so.

Reimplemented from erhic::VirtualEventFactory.

Definition at line 169 of file Pythia6EventBuilder.cxx.
