Channel & fiber queue

Sergiy

Consider following code:

_executionFiber = new PoolFiber();
_executionFiber.Start();
InfoChannel.Subscribe(_executionFiber, SomeMethod);

Will SomeMethod run in _executionFiber's queue? I mean - will the functionality be the same as

_executionFiber.Enqueue(SomeMethod)

?

I'm not a retlang expert and Ben is not around now. He will answer in a while.

Despite this, in the first code snippet you subscribe to whatever happens in the InfoChannel. SomeMethod is then used whenever the _executionFiber executes messages from the InfoChannel.
The second snippet Enqueues something into the _executionFiber. SomeMethod is the message and being executed when the fiber executes your message. This is a one-time thingy.

I think

I agree with you, Tobias. First code snippet could be executed many times, while second one - only once. But that doesn't matter here. The question is - will the method that is subscribed via channel, execute in fiber's queue?

Tobias

Ah, I didn't get that.
Yes. The _executionFiber is the execution context for the subscription. Each subscribe can have it's own execution thread/context.
