All Implemented Interfaces:

Serializable, Comparator<OxmFieldType>

public class OxmFieldTypeComparator
extends Object
implements Comparator<OxmFieldType>, Serializable

A customized comparator which defines how to compare different OxmFieldType.

In the flowmod match, OpenFlow standard match fields ( OxmBasicFieldType) always comes first, followed by the OxmExperimenterFieldType
