void genie::flux::GFluxFileConfigI::GetBranchInfo ( std::vector< std::string > &  branchNames, std::vector< std::string > &  branchClassNames, std::vector< void ** > &  branchObjPointers  )

virtual

allow caller to copy current status / ntuple entry info in the output file by providing copies of internal info

Assumes that branch object pointers will not change which may require either a copy be made or, if using the class directly for reading the branch, one must force ROOT to not autodelete: myns::MyClassType* fCurrMyClass = new myns::MyClassType; myTree->SetBranchAddress("bname",&fCurMyClass); //? TBranch* b = myTree->GetBranch("bname"); //? b->SetAutoDelete(false);

ensure vectors are sized sufficiently (or use .push_back()) branchNames[i] = "bname" branchClassNames[i] = "myns::MyClassType" branchObjPointers[i] = (void**)

Reimplemented in genie::flux::GNuMIFlux, and genie::flux::GSimpleNtpFlux.

Definition at line 54 of file GFluxFileConfigI.cxx.

  {
    // allow flux driver to report back current status and/or ntuple entry
    // info for possible recording in the output file by supplying
    // the class name, and a pointer to the object that will be filled
    // as well as a suggested name for the branch.

    // default is not to supply anything

pure virtual

first is primary method for loading root flux ntuple files and config others are alternatives that can be overloaded but have sensible defaults to fall back to calling the vector version

Implemented in genie::flux::GNuMIFlux, and genie::flux::GSimpleNtpFlux.

    // generated event statistics without requiring enormous beam simulation
    // statistics.
    // That option determines how many times the driver is going to cycle
    // through the input flux ntuple.
    // With ncycle=0 the flux ntuple will be recycled an infinite amount of
    // times so that the event generation loop can exit only on a POT or
    // event num check.

    fNCycles = TMath::Max(0L, ncycle);
  }

void genie::flux::GFluxFileConfigI::SetUpstreamZ ( double  z0 )

virtual

Definition at line 73 of file GFluxFileConfigI.cxx.

  {
    // The flux neutrino position (x,y) is given on the user specified
    // flux window.  This method sets the preferred user coord starting z
    // position upstream of detector face. Each flux neutrino will be
    // backtracked from the initial flux window to the input z0.
    // If the value is unreasonable (> 10^30) then the ray is left on
    // the flux window.
