> Key: TINKERPOP-1554
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1554
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.2.3
> Reporter: Marko A. Rodriguez
> Assignee: Marko A. Rodriguez
>
> Currently {{has('name')}} compiles to {{filter(values('name'))}}. This is bad
> for a few reasons:
> 1. Its slower than a direct step.
> 2. Its nested traversals which increases reasoning time of strategies.
> 3. Its not clear from bytecode what it going on.
> I propose:
> {code}
> public class HasPropertyStep<S extends Element> implements FilterStep<S> {
> private String propertyKey;
> public boolean filter(final Traverser.Admin<S> traverser) {
> return traverser.get().properties(propertyKey).hasNext();
> }
> }
> {code}
