ROOT::Experimental::Internal::RNTupleSerializer::RContext Class Reference

The serialization context is used for the piecewise serialization of a descriptor.

During header serialization, the mapping of in-memory field and column IDs to on-disk IDs is built so that it can be used for the footer serialization in a second step.
