Reactive Extensions API in depth: even more Zip

Posted By: Jeffrey van Gogh | Dec 9th, 2009 @ 9:31 AM | 32,496 Views | 4 Comments
In the previous episode this episode of the Rx API in depth, Jeff talked about the Zip operator in Rx.

In this episode, Jeff dives even deeper in the semantics of Zip, and shows what happens in OnCompleted, OnError and infinite stream cases.

excuse me - do you has a flavor?

Rx is very interest. But these 2 videos on Zip were very uninforming. Sad

 

Please, show us some code, go deep, show us how to use it in code!

Cool short videos on Rx framework.

 

What I find odd about Zip operator is that the combination of error and infinite stream does not result in error. This seems not coherent with Merge operator.

Clearly that was a mistake in the presentation.  The only time Zip would never produce a value is if either stream stops producing values and never trigger done or error (it could also be that both enter this state).  Furthermore, there is a race condition between done and error during zipping which makes the outcome unpredictable.  It all depends on which event is observed first (done or error).

 

Please post a follow up video to this to correct this one.  Thanks!

I think Bjorg is correct, wouldn't Zip throw an error in the case of ┴ and an exception?
