Detailed Description

       A runlist is used to restrict concurrent exection to a limited set of
       concurrent sessions, much like a semaphore.

       However, the runlist differs in that it notifies objects when they
       become ready to run, rather than requiring them to wait and 'block' for
       the semaphore count to become low enough to continue.

Constructor & Destructor Documentation

   ost::Runlist::Runlist (unsignedcount = 1)
       Create a new runlist with a specified limit.

       Parameters:
           count limit before wait queuing.

Member Function Documentation

   bool ost::Runlist::add (Runable *run)
       Add a runable object to this runlist. If the number of entries running
       is below the limit, then add returns true otherwise the entry is added
       to the list.

       Returns:
           true if immediately ready to run

       Parameters:
           run pointer to runable object.

   void ost::Runlist::check (void) [protected]
   void ost::Runlist::del (Runable *run)
       Remove a runable object from the wait list or notify when it is done
       running so that the used count can be decremented.

       Parameters:
           run pointer to runable object.

   void ost::Runlist::set (unsignedlimit)
       Set the limit.

       Parameters:
           limit to use.
