  18. def test(s: TablePartitionStats, e: ExprNodeEvaluator): Boolean

    Test whether we should keep the split as a candidate given the filter predicates.

    Test whether we should keep the split as a candidate given the filter predicates. Return true if the split should be kept as a candidate, false if the split should be pruned.

    s and s.stats must not be null here.
