///  * This interface does not strictly define what happens when the priority of an
///  * object is changed.  An implementation of this interface is free to define
///  * the side-effects of changing the priority of an object.  In some cases,
///  * changing the priority of an object may be disallowed (resulting in an
    ///  * exception being thrown) or may simply be ignored.
