template<int DIMENSIONS, class PRECISION>
class ROOT::Detail::THistImplBase< DIMENSIONS, PRECISION >

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).
