Andrea C commented on TINKERPOP-3159:
-------------------------------------
This does seem like it would be a useful feature and hopefully not difficult to
implement given how the `path` step supports similar functionality with `to`
and `from`.

> Key: TINKERPOP-3159
> URL: https://issues.apache.org/jira/browse/TINKERPOP-3159
> Project: TinkerPop
> Issue Type: Improvement
> Components: language
> Affects Versions: 3.7.3
> Reporter: Christopher Smith
> Priority: Major
>
> I have a reusable query fragment in a business application that starts at a
> "user" vertex and enumerates some various resources the user has access to,
> using {{tree()}} to report structure. However, the {{tree}} step always
> reports the entire traverser path from {{{}g.V(){}}}, with no way to limit
> it—\{{sideEffect}}, {{{}local{}}}, and so on either don't reset it or
> entirely clear the history. I would like to be able to use {{from}} on
> {{tree}} in the same manner as on {{path}} so that I could do this:
> {code:java}
> def resources(GraphTraversal<?, Vertex> userVertex) {
> userVertex.as('user')
> .out('Controls').as('widgets')
> .out('Contains').as('parts')
> // blah blah
> .tree('resourceTree').from('user')
> .project //...
> }{code}
