Method Detail

traversal

public static GraphTraversalSource traversal()

Create a GraphTraversalSource that will be used to build Traversals for using with the statementFromTraversal(org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.GraphTraversal<S, E>) method.

Iterating on a GraphTraversalSource created with this method will not work.

Returns:

a simple and non-iterable traversal source, associated to a EmptyGraph.

traversal

public static GraphTraversalSource traversal(DseSession dseSession,
                                             GraphOptions graphOptions)

Create a GraphTraversalSource initialized to work remotely with a DSE Graph server, communicating via the DataStax Enterprise Java Driver.

Parameters:

dseSession - an initialized and active session created with a DseCluster that will be used internally to communicate with the DSE server. All of the configurations made on the DseSession's creation will be effective when the traversal source is used.

graphOptions - configurations to use for this traversal source. The options on this object will override the ones defined on the GraphOptions of the DseCluster behind the DseSession input.

Returns:

a remotely connected and initialized traversal source that can be used right away.

traversal

public static GraphTraversalSource traversal(DseSession dseSession)

Create a GraphTraversalSource initialized to work remotely with a DSE Graph server, communicating via the DataStax Enterprise Java Driver.

Parameters:

dseSession - an initialized and active session created with a DseCluster that will be used internally to communicate with the DSE server. All of the configurations made on the DseSession's creation will be effective when the traversal source is used.

Returns:

a remotely connected and initialized traversal source that can be used right away.

statementFromTraversal

public static <S,E> GraphStatement statementFromTraversal(GraphTraversal<S,E> traversal)

Create an initialized GraphStatement from a GraphTraversal to use directly with a DseSession.

Parameters:

traversal - the Traversal to use to create the statement.

Returns:

a statement executable in a DseSession.executeGraph(java.lang.String) or DseSession.executeGraphAsync(java.lang.String) call.
