Detailed Description

Abstract base class for event builders. Due to how ROOT handles allocating branch objects, we take care of creating and filling branches in this class also.

Member Typedef Documentation

typedef std::pair<TString, TObject*> erhic::VirtualEventFactory::NamedObjects

run information (like cross section) is usually saved with a LogReader that parses a separate file and is completely independent from the factory, forester, Plant() mechanism, only connected in BuildTree.cxx. For some formats (like HepMC), that won't work; the best information is gained from the last event. A hacky but flexible fix: Allow factories to maintain a TObjArray of things to write at the end. Side effect: Could also be used for QA histos or the like.

Member Function Documentation

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

inlinevirtual

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 in erhic::Pythia6EventBuilder, erhic::hadronic::Pythia6EventFactory, Smear::EventFactory< T >, Smear::EventFactory< erhic::hadronic::EventSmear >, and Smear::EventFactory< Smear::Event >.

Here is the caller graph for this function:

virtual VirtualEvent* erhic::VirtualEventFactory::Create ( )

pure virtual

Returns a new event instance.

Implemented in erhic::EventFromAsciiFactory< T >, erhic::EventFromAsciiFactory< T >, Smear::HadronicEventBuilder, erhic::Pythia6EventBuilder, Smear::EventDisFactory, erhic::hadronic::Pythia6EventFactory, Smear::EventFactory< T >, Smear::EventFactory< erhic::hadronic::EventSmear >, and Smear::EventFactory< Smear::Event >.

Referenced by Poacher::GetNextEvent(), and erhic::Forester::Plant().

Here is the caller graph for this function:

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

pure 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.

Implemented in erhic::EventFromAsciiFactory< T >, erhic::Pythia6EventBuilder, erhic::hadronic::Pythia6EventFactory, Smear::EventFactory< T >, Smear::EventFactory< erhic::hadronic::EventSmear >, and Smear::EventFactory< Smear::Event >.

Referenced by Poacher::EventName().

Here is the caller graph for this function:

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

inlinevirtual

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

Reimplemented in Smear::EventFactory< T >, Smear::EventFactory< erhic::hadronic::EventSmear >, Smear::EventFactory< Smear::Event >, erhic::hadronic::Pythia6EventFactory, and erhic::Pythia6EventBuilder.
