Class VersionDuplicateHandler

java.lang.Object

org.somda.sdc.biceps.consumer.preprocessing.VersionDuplicateHandler

All Implemented Interfaces:

StatePreprocessingSegment

public class VersionDuplicateHandler
extends Object
implements StatePreprocessingSegment

Preprocessing segment that removes changes from modification sets that have already been applied on the MDIB storage before.

This typically happens after a description change when states are sent out in addition to the description modification message. Those additional elements will be thrown away.
