[jira] [Commented] (TINKERPOP3-782) map(Traversal) should declare requirements of child

["Marko A. Rodriguez (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TINKERPOP3-782?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14650473#comment-14650473 ] 

Marko A. Rodriguez commented on TINKERPOP3-782:
-----------------------------------------------

I fixed this up a bit. Two things:

1. None of the {{TraversalXXXSteps}} have a requirement save for what their children require. Thus:

{code}
    @Override
    public Set<TraverserRequirement> getRequirements() {
        return this.getSelfAndChildRequirements();
    }
{code}

2. You only did {{TraversalMapStep}} and {{TraversalFlatMapStep}}. I added the above to {{TraversalSideEffectStep}} and {{TraversalFilterStep}}.
