Interface RemoteTraversalSideEffects

All Superinterfaces:

AutoCloseable, Cloneable, Serializable, TraversalSideEffects

All Known Implementing Classes:

AbstractRemoteTraversalSideEffects, DriverRemoteTraversalSideEffects, EmbeddedRemoteTraversalSideEffects

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.
