candidatesFor

public List<RuleIndex.Candidate> candidatesFor(Element element)

The candidates whose bucket key the element satisfies, in cascade order. A superset of the actually matching alternatives; callers still run the matcher on each candidate.

public List<RuleIndex.Candidate> allCandidates()

Every indexed candidate, in cascade order.
