Daniel Kuppitz commented on TINKERPOP3-762:
-------------------------------------------
For each incoming object; it's just a simple flatMap.
[~mhfrantz]: You won't need those complicated match patterns:
*Query 1:*
{code}
g.V().hasLabel('company').as('c','cv').
V().hasLabel('person').as('p','pv').dedup('c','p').
select('c','p').by('cname').by('pname').where('c', eq('p')).
addOutE('pv', 'worksFor', 'cv')
{code}
*Query 2:*
{code}
g.V().hasLabel('person').as('a').
V().hasLabel('person').as('b').
where('a', neq('b')).
addOutE('a', 'relatesTo', 'b').
addOutE('b', 'relatesTo', 'a')
{code}
> Allow mid-traversal V() (and E())

> Key: TINKERPOP3-762
> URL: https://issues.apache.org/jira/browse/TINKERPOP3-762
> Project: TinkerPop 3
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.0.0-incubating
> Reporter: Daniel Kuppitz
> Assignee: Marko A. Rodriguez
>
> We should allow mid-traversal {{V()}} and {{E()}}. It shouldn't be a
> technical problem, since we always know the traversal source, thus it's just
> a simple {{flatMap}}. Vendors could then implement mid-traversal global index
> lookups.
> *Example*:
> {code}
> g.V().hasLabel("company").has("name", "DataStax").in("worksFor").as("dse").
> V().hasLabel("company").has("name", "Aurelius").in("worksFor").as("ae").
> addOutE("dse", "knows", "ae", "since", "02/2015")
> {code}
