stephen mallette closed TINKERPOP-882.
--------------------------------------
Resolution: Incomplete
We all know this is a problem at this point....nothing has really presented
itself as a nice solution. Going to close this with the idea that if a new idea
pops up with a specific approach to making an improvement then we'll create a
new JIRA around that.
> Develop a less error prone way for rewriting strategies
> -------------------------------------------------------
>
> Key: TINKERPOP-882
> URL: https://issues.apache.org/jira/browse/TINKERPOP-882
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.0.2-incubating
> Reporter: Marko A. Rodriguez
> Priority: Major
>
> When someone writes a {{TraversalStrategy}} it is of the nature:
> {code}
> if(step instanceof SelectStep && ((SelectStep)step).getLocalChildren().size()
> > 1) {
> TraversalHelper.insertStep(new IdentityStep(), step, traversal);
> }
> {code}
> It can start to get hairy looking fast. It would be great if we could study
> the strategies we have thus far and see if there are patterns we can extract
> encapsulate such behaviors in new methods in {{TraversalHelper}}. I don't
> have any good ideas on how to do this, but I think we need it. My only
> thought was a "regular expression" language for our traversals so we can
> pattern match ON the traversal.
