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

Interface class for THistImpl.

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