final void scala::actors::FJTaskRunner::push ( final FJTask  r  )  [inline]

Push a task onto DEQ. Called ONLY by current thread.

Definition at line 396 of file FJTaskRunner.java.

References base, deq, put(), slowPush(), and top.

    int t = top;

      This test catches both overflows and index wraps.  It doesn't
      really matter if base value is in the midst of changing in take. 
      As long as deq length is < 2^30, we are guaranteed to catch wrap in
      time since base can only be incremented at most length times
      between pushes (or puts). 

    if (t < (base & (deq.length-1)) + deq.length) {

      deq[t & (deq.length-1)].put(r);
      top = t + 1;

    else  // isolate slow case to increase chances push is inlined
      slowPush(r); // check overflow and retry
