Class RelationIdentifierGraphBinarySerializer

java.lang.Object

org.janusgraph.graphdb.tinkerpop.io.binary.JanusGraphTypeSerializer<RelationIdentifier>

org.janusgraph.graphdb.tinkerpop.io.binary.RelationIdentifierGraphBinarySerializer

All Implemented Interfaces:

org.apache.tinkerpop.gremlin.structure.io.binary.types.CustomTypeSerializer<RelationIdentifier>, org.apache.tinkerpop.gremlin.structure.io.binary.TypeSerializer<RelationIdentifier>

public class RelationIdentifierGraphBinarySerializer
extends JanusGraphTypeSerializer<RelationIdentifier>

Serialize and deserialize relation identifier To distinguish between string and long IDs, we use an extra byte as marker. Technically, we could save this byte by leveraging the fact that long-type IDs are always non-negative, but it would require changes from TinkerPop side as well.
