Member Function Documentation

void Event::AddLast ( ParticleMCS * particle )

virtual

Add a new track to the end of the track list. The track must be allocated via new and is subsequently owned by the Event.

References particles.

const ParticleMCS * Event::BeamHadron ( ) const

inlinevirtual

Returns a pointer to the incident hadron beam particle. See also notes in BeamLepton().

In the standard eRHIC Monte Carlo format, the incident hadron beam is assumed to be the second particle in the particle list.

Implements erhic::EventDis.

References particles.

const ParticleMCS * Event::BeamLepton ( ) const

inlinevirtual

Returns a pointer to the incident lepton beam particle. Returns a NULL pointer if the particle cannot be located in the event. IMPORTANT - DO NOT DELETE THE POINTER OR BAD THINGS WILL HAPPEN!

In the standard eRHIC Monte Carlo format, the incident lepton beam is assumed to be the first particle in the particle list. This is the behaviour implemented here. Derived classes can implement other selection mechanisms depending on their data format.

Implements erhic::EventDis.

void Event::ClearParticles ( )

Here is the caller graph for this function:

const ParticleMCS * Event::ExchangeBoson ( ) const

inlinevirtual

Returns a pointer to the exchanged boson. See also notes in BeamLepton().

In the standard eRHIC Monte Carlo format, the exchanged boson is assumed to be the third particle in the particle list.

Implements erhic::EventDis.
