Subject [jira] [Commented] (TINKERPOP3-760) Make loop counter accessible within repeat()
Date Sat, 01 Aug 2015 17:48:04 GMT

    [ https://issues.apache.org/jira/browse/TINKERPOP3-760?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14650474#comment-14650474
] 

Marko A. Rodriguez commented on TINKERPOP3-760:
-----------------------------------------------

The problem with the {{as()}}-model is that the labels refers to two things -- the object
in the step at that point AND the step itself. We have removed (I believe completely) the
use of {{as()}} as a reference to a step (only to the path element generated by that step).

We could do something janky like this:

{code}
repeat('a', out().repeat('b', in().loops('a')))
{code}

...where the default [~dkuppitz] {{loops()}} is simply the current loop on the stack.

> Currently we can access the loop counter in a lambda:
> {code}
> .filter {it.loops() < 3}
> {code}
> Would be nice to have a step to access the counter:
> {code}
> .where(loops().is(lt(3)))
> {code}
