Class TakeLowerNodeIdentifierStrategy

  • All Implemented Interfaces:
    java.io.Serializable, MergeForgivenessStrategy
    public class TakeLowerNodeIdentifierStrategy
extends java.lang.Object
implements MergeForgivenessStrategy
    A MergeForgivenessStrategy which returns a FeatureChange which takes the lower start or end node identifier when two edges conflict on that value. This protects against mutations that generate nodes that already exist in the underlying atlas.
