KMatrixPropMap map_
The map used to store the propagator information.
const TString & name() const
The parameter name.
LauKMatrixPropFactory()
Private constructor (to ensure the singleton nature of this class)
LauKMatrixPropagator * getPropagator(const TString &name, const TString &paramFileName, Int_t resPairAmpInt, Int_t nChannels, Int_t nPoles, Int_t rowIndex)
Retrieve the propagator if it already exists, otherwise create one.
