Interface RemoteTraversal<S,E>

All Superinterfaces:

AutoCloseable, Cloneable, Iterator<E>, Serializable, Traversal<S,E>, Traversal.Admin<S,E>

All Known Implementing Classes:

AbstractRemoteTraversal, DriverRemoteTraversal, EmbeddedRemoteTraversal

public interface RemoteTraversal<S,E>
extends Traversal.Admin<S,E>

A RemoteTraversal is returned from RemoteConnection.submitAsync(Bytecode). It is iterated from within RemoteStep using Traversal.Admin.nextTraverser(). Implementations should typically be given a "result" from a remote source where the traversal was executed. The "result" should be an iterator which preferably has its data bulked.

Note that internally Traversal.Admin.nextTraverser() is called from within a loop (specifically in AbstractStep.next() that breaks properly when a NoSuchElementException is thrown. In other words the "results" should be iterated to force that failure.

Method Detail

getSideEffects

@Deprecated
RemoteTraversalSideEffects getSideEffects()

Deprecated. as of release 3.3.8, not directly replaced, see Admin#getSideEffects() for more information.

Returns remote side-effects generated by the traversal so that they can be accessible to the client. Note that "side-effect" refers to the value in "a" in the traversal g.V().aggregate('a').values('name').

Specified by:

getSideEffects in interface Traversal.Admin<S,E>

Returns:

The traversal sideEffects
