Class AnonymousTraversalSource<T extends TraversalSource>

java.lang.Object

org.apache.tinkerpop.gremlin.process.traversal.AnonymousTraversalSource<T>

public class AnonymousTraversalSource<T extends TraversalSource>
extends Object

Provides a unified way to construct a TraversalSource from the perspective of the traversal. In this syntax the user is creating the source and binding it to a reference which is either an existing Graph instance or a RemoteConnection.

Method Summary

Modifier and Type	Method and Description
static AnonymousTraversalSource<GraphTraversalSource>	traversal() Constructs an AnonymousTraversalSource which will then be configured to spawn a GraphTraversalSource.
static <T extends TraversalSource> AnonymousTraversalSource<T>	traversal(Class<T> traversalSourceClass) Constructs an AnonymousTraversalSource which will then be configured to spawn the specified TraversalSource.
T	withEmbedded(Graph graph) Creates the specified TraversalSource binding an embedded Graph as its reference such that traversals spawned from it will execute over that reference.
T	withGraph(Graph graph) Deprecated. As of release 3.4.9, replaced by withEmbedded(Graph)
T	withRemote(Configuration conf) Creates a TraversalSource binding a RemoteConnection to a remote Graph instances as its reference so that traversals spawned from it will execute over that reference.
T	withRemote(String configFile) Creates a TraversalSource binding a RemoteConnection to a remote Graph instances as its reference so that traversals spawned from it will execute over that reference.

Method Detail

traversal

public static AnonymousTraversalSource<GraphTraversalSource> traversal()

Constructs an AnonymousTraversalSource which will then be configured to spawn a GraphTraversalSource.

traversal

public static <T extends TraversalSource> AnonymousTraversalSource<T> traversal(Class<T> traversalSourceClass)

Constructs an AnonymousTraversalSource which will then be configured to spawn the specified TraversalSource.

withRemote

public T withRemote(String configFile)
             throws Exception

Creates a TraversalSource binding a RemoteConnection to a remote Graph instances as its reference so that traversals spawned from it will execute over that reference.

Parameters:

configFile - a path to a file that would normally be provided to configure a RemoteConnection

Throws:

Exception

withRemote

public T withRemote(Configuration conf)

Creates a TraversalSource binding a RemoteConnection to a remote Graph instances as its reference so that traversals spawned from it will execute over that reference.

Parameters:

conf - a Configuration object that would normally be provided to configure a RemoteConnection

withGraph

public T withGraph(Graph graph)

Deprecated. As of release 3.4.9, replaced by withEmbedded(Graph)

Creates the specified TraversalSource binding an embedded Graph as its reference such that traversals spawned from it will execute over that reference.

withEmbedded

public T withEmbedded(Graph graph)

Creates the specified TraversalSource binding an embedded Graph as its reference such that traversals spawned from it will execute over that reference.
