Does Gracefull shutdown Mbean support waiting time argument?

[ext2]

Hi:
        Camel support graceful shutdown feature. When the camelContext is
stopped, camel will try to stop application gracefully until the time
expired; 

        Some-times the system manager  may required to try to stop the
application , and if the application cannot be stopped in time, the system
manager will have another chance to decide to shutdown the application
robustly or not;
        That's to say , does the camel graceful shutdown strategy support
such feature as following?

        boolean stop(Boolean robust, int waitingTime);
        if ${robust} == false, camel will try to stop application in
${waitingtime) gracefully. if ${waitingTime) expired, camel will not stop
application robustly.
        If ${robust} == true, camel will try to stop application in
${waitingTime), if ${waitingTime)expired, camel will shutdown application
robustly;

Thanks any suggestion
