An interface capable of sorting fields. Implement this interface if you want to customize the
field order in which XStream serializes objects.
author: Guilherme Silveira since: 1.2.2
Sort the fields of a type. The method will be called with the class type that contains
all the fields and a Map that retains the order in which the elements have been added.
The sequence in which elements are returned by an iterator defines the processing order
of the fields. An implementation may create a different Map with similar semantic, add
all elements of the original map and return the new one.
Parameters: type - the class that contains all the fields Parameters: keyedByFieldKey - a Map containing a FieldKey as key element and ajava.lang.reflect.Field as value. a Map with all the entries of the original Map since: 1.2.2
