ROOT::Experimental::Detail::RRawPtrWriteEntry Class Reference

A container of const raw pointers, corresponding to a row in the data set.

This class can be used to write constant data products in frameworks. All other users are encouraged to use the API provided by REntry, with safe interfaces, type checks, and shared object ownership.
