ROOT::Experimental::Detail::RFieldBase::RValue Class Reference

Points to an object with RNTuple I/O support and keeps a pointer to the corresponding field.

Only fields can create RValue objects through generation, binding or splitting. An RValue object can be owning or non-owning. Only RField::GenerateValue creates owning RValues. Owning RValues destroy and free the object upon destruction.
