public interface QueryRunner<T>

This interface has two similar run() methods. run(Query, Map) is legacy and run(QueryPlus, Map) is the new one. Their default implementations delegate to each other. Every implementation of QueryRunner should override only one of those methods. New implementations should override the new method: run(QueryPlus, Map).

Method Summary
