---------------------------------------------

             Summary: Provide TraverserSet.detach()/attach() methods.
                 Key: TINKERPOP-1203
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1203
             Project: TinkerPop
          Issue Type: Improvement
          Components: process
    Affects Versions: 3.1.1-incubating
            Reporter: Marko A. Rodriguez


I do this all the time:

{code}
final TraverserSet<E> traverserSet = new TraverserSet<>();
traversal.getEndStep().forEachRemaining( traverser -> {
  traverser.detach();
  traverserSet.add(traverser)
});
return traverserSet
{code}

Sorta ghetto. Be nice if we had this functionality:

{code}
traverserSet.detach()
{code}

We could also provide:

{code}
traverserSet.attach(Attachable.Method)
traverserSet.attach(Predicate<Traverser<S>>, Attachable.Method) // this is 
important cause you don't want to re-attach paths alot of the time and 
DetachedVertexProperty has a transient that causes NPEs (hack around).
{code}

Also, we could then have:

{code}
Traversal.addStarts(TraverserSet<S>)
{code}

This would "bulk insert" without iteration by just writing directly to 
{{ExpandableIterator}}.
