Marko A. Rodriguez commented on TINKERPOP3-762:
-----------------------------------------------
[~dkuppitz] Please do the following.
1. Add more test cases to {{GraphStep}}.
2. Write the documentation for "Graph Step" (include CAUTION: about indicies).
3. Write {{GraphStepTest}} to verify {{hashCode()}} (and you may need to make a
{{hashCode()}} impl for {{GraphStep}}.
4. Please write {{TinkerGraphStepStrategyTest}} and
{{Neo4jGraphStepStrategyTest}} to ensure they you are getting "has container
fold in."
To point 4, you can probably just copy/paste the test case for
{{TinkerGraphStepStrategyTest}} to {{Neo4jGraphStepStrategyTest}} as the
implementation for both is nearly identical. Though, be sure we have both tests
as they may evolve independently.
> 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: 3.0.1-incubating
> Reporter: Daniel Kuppitz
> Assignee: Daniel Kuppitz
> Fix For: 3.1.0-incubating
>
>
> 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}
