ROOT::Experimental::Detail::RNTupleMetrics Class Reference
RNTuple

A collection of Counter objects with a name, a unit, and a description.

The class owns the counters.

If the environment variable ROOT_EXPERIMENTAL_EXPORT_RNTUPLE_METRICS is set, metrics are automatically enabled on construction, and any counter added afterwards through MakeCounter() is enabled as well.
