Package org.apache.tinkerpop.gremlin.process.remote

Class EmbeddedRemoteConnection

java.lang.Object

org.apache.tinkerpop.gremlin.process.remote.EmbeddedRemoteConnection

All Implemented Interfaces:

AutoCloseable, RemoteConnection

public class EmbeddedRemoteConnection
extends Object
implements RemoteConnection

Allows a RemoteConnection to be submitted to a "local" Graph instance thus simulating a connection to a remote source. Basic usage is as follows:

 
 // Using TinkerGraph here but any embedded Graph instance would suffice
 Graph graph = TinkerFactory.createModern();
 GraphTraversalSource g = graph.traversal();

 // setup the remote as normal but give it the embedded "g" so that it executes against that
 GraphTraversalSource simulatedRemoteG = traversal().with(new EmbeddedRemoteConnection(g));
 assertEquals(6, simulatedRemoteG.V().count().next().intValue());

Description copied from interface: RemoteConnection

Submits Traversal GremlinLang to a server and returns a promise of a RemoteTraversal. The RemoteTraversal is an abstraction over two types of results that can be returned as part of the response from the server: the results of the Traversal itself and the side-effects that it produced.

Specified by:

submitAsync in interface RemoteConnection

Throws:

RemoteConnectionException

close

public void close()
           throws Exception

Specified by:

close in interface AutoCloseable

Throws:

Exception
