public class LongIdJsonRelationship
extends JsonRelationship<Long>

JsonRelationship with Long custom ID. Can be easily used to directly represent Neo4j relationships by using constructors without supplying NodeIdTransformer or RelationshipIdTransformer. In these cases, TrivialNodeIdTransformer and TrivialRelationshipIdTransformer are used and custom node/relationship IDs become the internal Neo4j node IDs. It is recommended, however, that true custom IDs are used, such as UUIDs.
