EmbeddedRemoteTraversal

public EmbeddedRemoteTraversal(Traversal<S,E> t)

Method Detail

nextTraverser

public Traverser.Admin<E> nextTraverser()

Description copied from class: AbstractRemoteTraversal

Note that internally AbstractRemoteTraversal.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.

Specified by:

nextTraverser in interface Traversal.Admin<S,E>

Specified by:

nextTraverser in class AbstractRemoteTraversal<S,E>

getSideEffects

public RemoteTraversalSideEffects getSideEffects()

Description copied from interface: RemoteTraversal

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').

Returns:

The traversal sideEffects

hasNext

public boolean hasNext()

next

public E next()
