Description copied from interface:FieldKeySorter
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.- Specified by:
sort
in interfaceFieldKeySorter
- Parameters:
type
- the class that contains all the fieldskeyedByFieldKey
- a Map containing aFieldKey
as key element and aField

- a Map with all the entries of the original Map
