Field Detail

g

public static final org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.GraphTraversalSource g

IMPORTANT: As of Tinkerpop 3.3.5, you should no longer use this shortcut if you intend to connect the traversal to DSE Graph using a remote connection, for example via the remoteConnectionBuilder(com.datastax.oss.driver.api.core.CqlSession) method declared below. Instead of:

 DseSession session = ...;
 RemoteConnection remoteConnection = DseGraph.remoteConnectionBuilder(session).build();
 GraphTraversalSource g = DseGraph.g.withRemote(remoteConnection);
 

You should now use AnonymousTraversalSource.traversal(), and adopt the following idiom:

 DseSession session = ...;
 RemoteConnection remoteConnection = DseGraph.remoteConnectionBuilder(session).build();
 GraphTraversalSource g = AnonymousTraversalSource.traversal().withRemote(remoteConnection);
 

A general-purpose shortcut for a non-connected TinkerPop GraphTraversalSource based on an immutable empty graph. This is really just a shortcut to EmptyGraph.instance().traversal();.

It can be used to create FluentGraphStatement instances (recommended); for ease of use you may statically import this variable.

Calling g.getGraph() will return a local immutable empty graph which is in no way connected to the DSE Graph server, it will not allow to modify a DSE Graph directly. To act on data stored in DSE Graph you must use traversals such as DseGraph.g.V(), DseGraph.g.addV/addE().
