> Implement GraphFilterStrategy as a default registration for GraphComputer
> -------------------------------------------------------------------------
>
> Key: TINKERPOP-1293
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1293
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.2.0-incubating
> Reporter: Marko A. Rodriguez
> Assignee: Marko A. Rodriguez
> Fix For: 3.2.1

>
> {{GraphFilterStrategy}} would be a {{TraversalStrategy}} for
> {{GraphComputers}}. It will inspect the {{Traversal}} and decide the
> {{computer.vertices(...).edges(...)}} to use.
> Some rules:
> 1. If the traversal is part of an OLAP chain, don't apply strategy.
> 2. If the traversal is persist edges, then don't {{edges(...)}} or
> {{vertices(...)}}.
> 3. If the traversal is persist vertex properties, then don't do
> {{vertices(...)}}.
> Shouldn't be too difficult. Basically looking for:
> 1. {{VertexStep}} labels for edges.
> 2. {{HasStep}} containers for vertices and edges.
> From there, we can get fancy with {{outE().has("stars",gt(4))}}-style
> {{edges(...)}}. However, basic element-label based filtering should be easy.
