//
// HepTH1F.cc - definition of class HepTH1F
//
// Intended to gain access to the protected members of the Root TH1F class.
//
// This class is used to import an existing histogram object from possibly
// some other manager and manufacture a temporary TH1F object with all the
// same characteristics as the original. That way, we can use the existing
// Root methods to implement the increment operators.
//
// Because of the eccentricities of the various managers, we do NOT manage
// to get some of the statistical sums quite right - in particular the
// sum of the squared weights - so the overall statistics should not be taken
// too seriously.
//
//   25-Feb-1999  J. Marraffino   Initial definition
//   21-Feb-2000  Walter Brown    Improved C++ standard compliance
