ROOT::Experimental::RNTupleDS::REntryRangeDS Struct Reference

The PrepareNextRanges() method populates the fNextRanges list with REntryRangeDS records.

The GetEntryRanges() swaps fNextRanges and fCurrentRanges and uses the list of REntryRangeDS records to return the list of ranges ready to use by the RDF loop manager.
