ROOT::Experimental::RNTupleCollectionWriter Class Reference

A virtual ntuple used for writing untyped collections that can be used to some extent like an RNTupleWriter.

This class is between a field and a ntuple. It carries the offset column for the collection and the default entry taken from the collection model. It does not, however, own an ntuple model because the collection model has been merged into the larger ntuple model.
