template<class DATA>
class ROOT::Experimental::Detail::RHistImplBase< DATA >

Interface class for RHistImpl.

RHistImpl is templated for a specific configuration of axes. To enable access through RHist, RHistImpl inherits from RHistImplBase, exposing only dimension (DIMENSION) and bin type (PRECISION).
