ROOT::Experimental::Detail::RNTupleTimer< WallTimeT, CpuTimeT > Class Template Reference

template<typename WallTimeT, typename CpuTimeT>
class ROOT::Experimental::Detail::RNTupleTimer< WallTimeT, CpuTimeT >

Record wall time and CPU time between construction and destruction.

Uses RAII as a stop watch. Only the wall time counter is used to determine whether the timer is active.
