              Detailed Description

              The dispatcher dispatches threads and, by that, puts the scheduler's decisions into action.

              The dispatcher manages the life pointer that refers to the currently active thread and performs the actual switching of processes. For single-core systems, a single life pointer is sufficient, as only a single thread can be active at any one time. On multi-core systems, every CPU core needs its own life pointer.

              static bool Dispatcher::isActive ( const Thread *  thread,
              unsigned *  cpu = nullptr 
              )
              inlinestatic

              Check if thread is currently active.

              Parameters
              threadPointer to the thread in question
              cpuwill receive the core number if cpu pointer is not nullptr and the thread is currently active
              Returns
              true if currently running, false otherwise
              void Dispatcher::go ( Thread *  first)
              static

              This method stores first as life pointer for this CPU core and triggers the execution of first thread.

              Note
              Only to be used for the first thread running on a CPU core.
              Parameters
              firstFirst thread to be executed on this CPU core.
              void Dispatcher::dispatch ( Thread *  next)
              static

              Updates the life pointer to next and issues a thread change from the old to the new life pointer.

              Parameters
              nextNext thread to be executed.
