public interface SqlMonitor

The vehicle interface definition, which can be used to monitor the duration of all SQL queries execution.

The implementation can be based for example on the Javasimon library. The standard implementation is an empty one, which just delegates the execution to the runner, for example

 public <E> List<E> runList(Runner runner, Class<E> resultClass) {
     return (List<E>) runner.run();
 }
