An AIR 3.7 application demonstrating the use of multiple Contexts with the Robotlegs AS3 micro-architecture - version 2

WIP

Modules, multiple Contexts and the ModularConnector (WIP)

In this demo the Shell loads 2 (Flex) Modules, Module_A and Module_B, and a popup window (Flex TitleWindow), which also loads a module, Module_C.

The Contexts communicate with each other through 2 ‘channels’, a named channel 'A-and-B', and a default channel.

The steps for enabling the multi contextual communication:

First of all, you need a contextView, a Context and the ModularityExtension (included in the MVCSBundle).

contextView

Let’s look at Module A’s root Display Object Container ModuleAView, which will be used as the "contextView" for this Context.

private var _robotlegsContext:ModuleAContext;
private function creationCompleteHandler(event:FlexEvent):void
{
        _robotlegsContext = new ModuleAContext(this);
}

ModuleAContext

public function ModuleAContext(view:DisplayObjectContainer)
{
    context = new Context() //1
        .install(MVCSBundle) //2
        .configure(MediatorsConfig, ModuleConnectorConfig) //3
        .configure(new ContextView(view)); //4
}

1. creates a Context
2. installs the ModularityExtension (included in the MVCSBundle already)
3. configures the communication channels (ModuleConnectorConfig)

ModuleConnectorConfig

moduleConnector.onDefaultChannel()
        .receiveEvent(ModularConnectorEvent.SHELL_TO_MODULES_MESSAGE);
moduleConnector.onChannel('A-and-B')
       .relayEvent(ModularConnectorEvent.A_TO_B_MESSAGE);
moduleConnector.onChannel('A-and-B')
        .receiveEvent(ModularConnectorEvent.B_TO_A_MESSAGE);

4. provides a contextView (ModuleAView)
5. dispatch events to other Contexts

   
       dispatch(new ModularConnectorEvent(ModularConnectorEvent.A_TO_B_MESSAGE, event.messagesVO));
       

6. listen to events from other Contexts

   
       addContextListener(ModularConnectorEvent.B_TO_A_MESSAGE, onMessageReceived, ModularConnectorEvent);
