ROOT::Experimental::RSliceSpec Class Referencefinal

Specification of a slice operation along one dimension.

using ROOT::Experimental::RSliceSpec;
// When not specifying a range, the slice will include all bins.
RSliceSpec full;
// In the following, assuming range is an RBinIndexRange.
RSliceSpec slice(range);
// Operations are specified with parameters.
RSliceSpec rebin(RSliceSpec::ROperationRebin(2));
RSliceSpec sum(RSliceSpec::ROperationSum{});
// Finally, it is possible to combine a range and an operation.
RSliceSpec sliceRebin(range, RSliceSpec::ROperationRebin(2));
RSliceSpec sliceSum(range, RSliceSpec::ROperationSum{});
