getReference()

bool Analysis::CalibrationDataInterfaceROOT::HadronisationReferenceHelper::getReference	(	const std::string &	spec,
		std::string &	ref
	)		const

Retrieve the (full) name of the reference histogram, given the hadronisation specification.

The return value will be false if the specification cannot be found, and true otherwise.

  // The return value is used to indicate whether the specification could be found.
  //
  //    spec:             hadronisation specification
  //    ref:              container name corresponding to this specification
