Hi, I think there will be loop in the graph. I use the example from online.
So i think it already define the uniqueness of traversal.
public TraversalExample( GraphDatabaseService db )
{
this.db = db;
// START SNIPPET: basetraverser
friendsTraversal = db.traversalDescription()
.breadthFirst()
.relationships( Rels.KNOWS )
.uniqueness( Uniqueness.RELATIONSHIP_GLOBAL );
// END SNIPPET: basetraverser
}
