 @NoOffset
 @Properties(inherit=arrow.class)
public class DictionaryFieldMapper
extends Pointer

\brief Map fields in a schema to dictionary ids The mapping is structural, i.e. the field path (as a vector of indices) is associated to the dictionary id. A dictionary id may be associated to multiple fields.
