Example 6 with RelationIdentifier

use of org.janusgraph.graphdb.relations.RelationIdentifier in project janusgraph by JanusGraph.

the class JanusGraphTest method testImplicitKey.

/**
 * Test the correct application of {@link org.janusgraph.graphdb.types.system.ImplicitKey}
 * to vertices, edges, and properties.
 * <p>
 * Additionally tests RelationIdentifier since this is closely related to ADJACENT and JANUSGRAPHID implicit keys.
