Swiz 1.0.0 RC1 was recently released so I've updated my custom metadata processors to work with it. Head over to Google Code to check out [MediateSignal] and [Resource]. Happy coding...

Joel Hooks created this RobotLegs/Signals demo. Ben Clinkinbeard then created this Swiz-version of Joel's demo. I then took Ben's demo and Swiz-ified it even more by using a custom [MediateSignal] processor. Here's the source.

[MediateSignal] is the Signal equivalent of [Mediate]. Here's an example:

[MediateSignal("galleryUpdatedSignal")]
public function galleryUpdated(gallery:Gallery):void

[MediateSignal] takes a Signal Bean name or type and adds the decorated method to the Signal (see GalleryThumbnailsPresentationModel for examples).

This is what I changed from Ben's demo:

• Created the MediateSignalProcessor
• Added [MediateSignal] metadata to the Signal listeners
• Made the Signal listeners public
• Named the Signal Beans
• Removed [PostConstruct] methods that added the Signal listeners
• Removed injected Signals that weren't being using to dispatch

[MediateSignal] makes using Signals in Swiz very parallel to using Events (especially if you define the Event dispatcher as a Bean and inject it by name). And just like Events, you only need to [Inject] the Signals into Beans who are dispatching Signals. I was pretty excited to create my first custom processor and play with Signals for the first time. Let me know what you think!

Disclaimer: I set up MediateSignalProcessor to also handle DeluxeSignals and remove listeners, though to be honest I didn't test those.

* Update: I've posted the processor on Google Code and it contains unit tests (including DeluxeSignals and removing listeners).

** Update: I've created a bare-bones example application: SWF and Source.
