Interface RemoteConnection

All Superinterfaces:

AutoCloseable

All Known Implementing Classes:

DriverRemoteConnection, EmbeddedRemoteConnection

public interface RemoteConnection
extends AutoCloseable

A simple abstraction of a "connection" to a "server" that is capable of processing a Traversal and returning results. Results refer to both the Iterator of results from the submitted Traversal as well as the side-effects produced by that Traversal. Those results together are wrapped in a Traversal.

<E> CompletableFuture<RemoteTraversal<?,E>> submitAsync(Bytecode bytecode)
                                                 throws RemoteConnectionException

Submits Traversal Bytecode 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.

Throws:

RemoteConnectionException

from

static RemoteConnection from(Configuration conf)

Create a RemoteConnection from a Configuration object. The configuration must contain a gremlin.remote.remoteConnectionClass key which is the fully qualified class name of a RemoteConnection class.
