Function Documentation

void AppendStdHep (  TClonesArray *  stdhep, const TClonesArray *  addon, const   TLorentzVector = TLorentzVector() )

Append one StdHep list to another (w/ potential offset). Referenced by HepevtModule::Get().

void clearCommon (  bool  fast = false  )

Clear /HEPEVT/ common block.

void closeBinary (  int &  fd  )

Close FORTRAN binary file (zero out filedescriptor). Referenced by WriteStdHepFileModule::CloseFile(), and HepevtModule::Config().

void dump (  const TClonesArray *  stdhep, int  verbose = 0 )

Formatted dump of StdHep array. verbose: 0=no vtx, 1=w/ vtx Referenced by HepevtModule::Ana(), BDUniquifyTestModule::Ana(), HepevtModule::Get(), and GenieModule::Get().

int fillCommon (  const TClonesArray *  stdhep, cvu_t  vtxCvu = UtilHepevt::k_mtomm, cvu_t  tCvu = UtilHepevt::k_sectomm )

Copy info from TClonesArray of TParticles into /HEPEVT/ common block. Referenced by WriteStdHepFileModule::Ana().

TClonesArray* getEmptyStdHep (  int  dfltsiz = -1  )

Construct a suitable TClonesArray of TParticles. Referenced by GenieModule::FillStdHep(), HepevtModule::FindOrCreateSimSnarlRecord(), and HepevtModule::Get().

int getNevHep (   )

Get/Set Event # in /HEPEVT/ common block.

int getNHep (   )

# of entries in /HEPEVT/ common block.
