Examples of org.nasutekds.server.types.SortKey

org.nasutekds.server.types.SortKey
This class defines a data structure that may be used as a sort key. It includes an attribute type and a boolean value that indicates whether the sort should be ascending or descending. It may also contain a specific ordering matching rule that should be used for the sorting process, although if none is provided it will use the default ordering matching rule for the attribute type.
