     /**
29 |  |
      * <p>A <b>ValveContext</b> is the mechanism by which a Valve can trigger the
30 |  |
      * execution of the next Valve in a Pipeline, without having to know anything
31 |  |
      * about the internal implementation mechanisms.  An instance of a class
32 |  |
      * implementing this interface is passed as a parameter to the
33 |  |
      * <code>Valve.invoke()</code> method of each executed Valve.</p>
34 |  |
      *
35 |  |
      * <p><strong>IMPLEMENTATION NOTE</strong>: It is up to the implementation of
36 |  |
      * ValveContext to ensure that simultaneous requests being processed (by
37 |  |
      * separate threads) through the same Pipeline do not interfere with each
38 |  |
      * other's flow of control.</p>
