Detailed Description

template<typename T, typename S, typename Q>
class RootHistCnv::RHistogramCnv< T, S, Q >

Generic converter to save/read AIDA_ROOT histograms using ROOT.

This converter shortcuts the AIDA binding and takes advantage of the underlying implementation of transient histograms using ROOT.

Note: THxY::Copy cannot be used - only THxY::Add !
