Nice. Thanks for taking the time to put this together. I’ve been building my latest project using the multicore PMVC, not because I need module support now, but because I don’t see any good reason NOT to use the MC version. Now down the road I can drop in a module, fix up the plumbing, and it is off to the races.

The puremvc pipes demo is great … but it’s too difficult to really understand…. I wanted to know if you could create a simple/basic pipes demo of your own? I really learned a lot from your modular Mortgage demo… could you maybe port that for use with pipes??

Joel agreed - I don’t see much benefit in *NOT* using the MultiCore version.

Mike, I’ve already ported the mortgage app demo to pipes - it was my ‘hello world’ into the pipes world. I’ll see if I can get around to posting it here today or tomorrow.

Thank you very much~~~
But why I don’t fond the modules file in the source file?
import com.dl.modules.pipes.interfaces.IPipeAwareModule;
import com.dl.modules.pipes.components.PipeAwareModule;

Please help~~

Thanks for the explanation.
Something I don’t understand: Do we need a Junction per module or can we create one alone junction for all the module?

By: Joshua

Amahi,
You’d want a junction at each module. Junction is where you’ll connect your pipes ‘together.’ A typical setup would include a junction for your ’shell’ app and junction for each loaded module.

The junctions are connected together via pipes.

The unction is the ‘integration’ point for your app / module into the pipe architecture.

hello, Joshua, thanks you very much~

But I have a question about the source of the demo, could you opensource the lib of that?

Thanks for your time ^_^
mani.

Could you openSource the lib of the demo?
Thanks~~

Hi, thanks for this..

May you provide a example?

By: Joshua

Y.Boy,
As soon as some time frees up, I’ll post some more examples and see if I can post the lib as well.

Josh,
Thank you so much for this explicit walkthrough. This was exactly what I needed right now to clear up some of the foggy patches in my understanding of the framework.

Josh,
I wonder if you have any thoughts on using pipes and loading swfs made in Flash in to the main Flex app rather than Flex modules? I have tried it out, making my movies main implement the IPipeAware interface, and creating junction mediator for it. It seems to works ok, but I feel there is something missing.

Russ,
Sure, there’s no ‘flex’ requirement for dynamic modules. If you dig back a bit further I posted on AS3 only dynamic modules - http://www.joshuaostrom.com/2008/05/24/as3-puremvc-dynamic-modules/ which might help you move forward, although it sounds like your well on your way!

Hello and thanks a lot for this post!

One simple question though, the best place to put the ApplicationJunctionMediator.as is in the “top level” package of my app or modules, right?

Cheers

I’m sorry if my question has been addressed before, but why bother using the pipes utility? All the examples I’ve seen are fairly complex for something as simple as making a module talk to it’s shell. It seems that you could do something as simple as have each side listen for a custom event….viola, done. I just don’t see the benefit of setting up all the pipes stuff.

By: Joshua

Joshua — Tue, 22 Sep 2009 12:13:03 +0000

Scottae,
It’s common to have your modules implement an interface and communicate via that contract. There’s not wrong with that at all.

Pipes benefit is realized when you’re working with a PureMVC app. You simply send your [PureMVC] notification and your done, your message is routed to it’s destination. That destination may be in the same module, or down/up a module, up/down multiple modules, etc.

Hope that helps.

Thanks guys,

I have started using Pipes in a largest application we have started recently. This tutorial helped me to in a great way.
