Method Detail

getValues

public static Iterable<Object> getValues(JanusGraphElement element,
                                         PropertyKey key)

getCompareId

public static long getCompareId(org.apache.tinkerpop.gremlin.structure.Element element)

attachProperties

public static void attachProperties(JanusGraphRelation element,
                                    Object... keyValues)

attachProperties

public static void attachProperties(JanusGraphVertex vertex,
                                    Object... propertyKeyValues)

This is essentially an adjusted copy&paste from TinkerPop's ElementHelper class. The reason for copying it is so that we can determine the cardinality of a property key based on JanusGraph's schema which is tied to this particular transaction and not the graph.

Parameters:

vertex -

propertyKeyValues -

getPropertyKeys

public static Set<String> getPropertyKeys(JanusGraphVertex v)
