ROOT::Internal::RFieldDescriptorBuilder Class Reference

A helper class for piece-wise construction of an RFieldDescriptor.

Dangling field descriptors describe a single field in isolation. They are missing the necessary relationship information (parent field, any child fields) required to describe a real RNTuple field.

Dangling field descriptors can only become actual descriptors when added to an RNTupleDescriptorBuilder instance and then linked to other fields.
