    Description copied from class: AbstractCreateStatementInterceptor
    
    no-op for this interceptor. no state is stored.
    
    Overrides:
    
    reset in class SlowQueryReport
    
    Parameters:
    parent - - the connection pool owning the connection
    con - - the pooled connection
  - poolClosed
```
public void poolClosed(ConnectionPool pool)
```
    Description copied from class: SlowQueryReport
    
    This method is invoked by a connection pool when the pool is closed. Interceptor classes can override this method if they keep static variables or other tracking means around. This method is only invoked on a single instance of the interceptor, and not on every instance created.
    
    Overrides:
    
    poolClosed in class SlowQueryReport
    
    Parameters:
    pool - - the pool that is being closed.
  - poolStarted
```
public void poolStarted(ConnectionPool pool)
```
    Description copied from class: SlowQueryReport
    
    This method is invoked by a connection pool when the pool is first started up, usually when the first connection is requested. Interceptor classes can override this method if they keep static variables or other tracking means around. This method is only invoked on a single instance of the interceptor, and not on every instance created.
    
    Overrides:
    
    poolStarted in class SlowQueryReport
    
    Parameters:
    pool - - the pool that is being closed.
  - reportFailedQuery
