Subject [jira] [Commented] (TINKERPOP-1355) Design HasContainer for extension
Date Mon, 04 Jul 2016 10:34:11 GMT

    [ https://issues.apache.org/jira/browse/TINKERPOP-1355?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15361141#comment-15361141

ASF GitHub Bot commented on TINKERPOP-1355:

Github user dkuppitz commented on the issue:

    I just implemented my proposed changes. Now we no longer get exceptions, but unexpected
    gremlin> g.V().hasId(within(new ArrayList()))
    gremlin> g.V().hasId(without(new ArrayList()))
    This should probably go into a separate ticket.

>                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1355
>             Project: TinkerPop
>          Issue Type: Improvement
>          Components: process
>    Affects Versions: 3.2.0-incubating
>            Reporter: Bryn Cooke
>            Priority: Critical
> Currently HasContainer is final. This means that Graph implementations cannot support
their own type systems across the entire traversal.
> Given the traversal:
> g.V.has('foo', nonTinkerpopType).out('bar').has('foo', nonTinkerpopType)
> Say that the initial traversal g.V.has('foo', nonTinkerpopType) is dealt with via strategy,
the non-Tinkerpop type can be dealt with. However the rest of the traversal is processed via
the default Tinkerpop pipeline, and as such it doesn't know how to deal with type conversions/comparisons
