---------------------------------------
Summary: Give access to HepPlanner.getVertexParents() to subclasses
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: The {{HepPlanner.getVertexParents()}} method is currently
private.
It has the following signature:
{code}
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.
