Class JanusGraphId

java.lang.Object

org.janusgraph.core.util.JanusGraphId

Deprecated.

This class does not produce valid JanusGraph vertex ids as it does not take into account partitioning bits used in vertex id assignment. Use IDManager, which can be obtained through StandardJanusGraph.getIDManager() and includes methods for converting a user id to (IDManager.toVertexId(long)) and from (IDManager.fromVertexId(long)) JanusGraph vertex id.

 IDManager idManager = ((StandardJanusGraph) graph).getIDManager();
 

@Deprecated
public class JanusGraphId
extends Object

Method Detail

toVertexId

public static long toVertexId(long id)

Deprecated. Use IDManager.toVertexId(long).

Converts a user provided long id into a JanusGraph vertex id. The id must be positive and can be at most 61 bits long. This method is useful when providing ids during vertex creation via Graph.addVertex(Object...).

Parameters:

id - long id

Returns:

a corresponding JanusGraph vertex id

fromVertexId

public static long fromVertexId(long id)

Deprecated. Use IDManager.fromVertexId(long)

Converts a JanusGraph vertex id to the user provided id as the inverse mapping of toVertexId(long).

Parameters:

id - JanusGraph vertex id (must be positive)

Returns:

original user provided id

fromVertexID

public static long fromVertexID(JanusGraphVertex v)

Deprecated. Use IDManager.fromVertexId(long)

Converts a JanusGraph vertex id of a given vertex to the user provided id as the inverse mapping of toVertexId(long).

Parameters:

v - Vertex

Returns:

original user provided id
