org.apache.tinkerpop.gremlin.process.remote.traversal

Interface RemoteTraversalSideEffects

All Superinterfaces:

AutoCloseable, Cloneable, Serializable, TraversalSideEffects

All Known Implementing Classes:

AbstractRemoteTraversalSideEffects, DriverRemoteTraversalSideEffects, EmbeddedRemoteTraversalSideEffects

Deprecated.

As of release 3.3.8, not directly replaced, prefer use of GraphTraversal.cap(String, String...) to return the result as part of the traversal iteration.

@Deprecated
public interface RemoteTraversalSideEffects
extends TraversalSideEffects, AutoCloseable

When a traversal is executed remotely, the ability to retrieve those side-effects (i.e. the value in "a" in the traversal g.V().aggregate('a').values('name')) can be exposed through this interface. As an example, with TinkerPop's DriverRemoteConnection that connects to Gremlin Server as a "remote", the side-effects are left on the server. The RemoteTraversalSideEffects implementation, in that case, lazily loads those side-effects when requested. Implementations should attempt to match the features of the locally processed DefaultTraversalSideEffects to keep consistency.

Modifier and Type	Method and Description
default void	close() Deprecated. If the "remote" that actually executed the traversal maintained resources that can be released, when the user is done with the side-effects, then this method can be used to trigger that release.
