ThreadScheduler

An example Scheduler using kernel threads.

This is an example Scheduler that mirrors the default scheduling behavior of creating one kernel thread per call to spawn. It is fully functional and may be instantiated and used, but is not a necessary part of the default functioning of this module.

class ThreadScheduler : Scheduler {

void start(void delegate() op);

void spawn(void delegate() op);

void yield();

ThreadInfo thisInfo [@property getter];

Condition newCondition(Mutex m);

}

Functions

newCondition Condition newCondition(Mutex m): Creates a new Condition variable. No custom behavior is needed here.
spawn void spawn(void delegate() op): Creates a new kernel thread and assigns it to run the supplied op.
start void start(void delegate() op): This simply runs op directly, since no real scheduling is needed by this approach.
yield void yield(): This scheduler does no explicit multiplexing, so this is a no-op.

Properties

thisInfo ThreadInfo thisInfo [@property getter]: Returns ThreadInfo.thisInfo, since it is a thread-local instance of ThreadInfo, which is the correct behavior for this scheduler.

Inherited Members

From Scheduler

start void start(void delegate() op): Spawns the supplied op and starts the Scheduler.
spawn void spawn(void delegate() op): Assigns a logical thread to execute the supplied op.
yield void yield(): Yields execution to another logical thread.
thisInfo ThreadInfo thisInfo [@property getter]: Returns an appropriate ThreadInfo instance.
newCondition Condition newCondition(Mutex m): Creates a Condition variable analog for signaling.
