> Key: CALCITE-7221
> URL: https://issues.apache.org/jira/browse/CALCITE-7221
> Project: Calcite
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.40.0
> Environment:
> Reporter: Claude Brisson
> Assignee: Claude Brisson
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.41.0
>
>
> The {{HepPlanner.getVertexParents()}} method is currently private.
> It has the following signature:
> {code:java}
> List<HepRelVertex> HepPlanner.getVertexParents(HepRelVertex)
> {code}
> in which HepRelVertex is already public.
> Exposing it avoids implementors redoing it in a way which is at least
> redundant, if not less efficient.
> My use case, which doesn't appear very exotic, is to crawl up a given plan
> from the scans. I'm sure there are others.
