The document discusses RL2, an ActionScript application framework that uses dependency injection. Some key features of RL2 include: 1) A fluent API for configuration and extensions that can be optionally added. 2) Bundles that contain pre-configured sets of extensions for common tasks like model-view-controller (MVC). 3) Built-in logging and tools for mapping events to commands, views to mediators, and more through extensions. 4) The framework handles bootstrapping the application context through configuration rather than extending base classes. 5) Several GitHub repositories provided as examples for integrating Robotlegs into common application types like Flash/Flex apps.

3. RL1 Recap
Dependency Injection
Commands
Mediators
https://github.com/robotlegs/robotlegs-framework/tree/master 3

4. RL2
As above, but with:
A fluent API
Extensions (opt-in)
Bundles (presets)
Configs
Logging (built-in)
Module autowiring

5. Dependency Injection
https://github.com/tschneidereit/SwiftSuspenders/ 5

6. Swiftsuspenders 2
injector.map(IService).toValue(service)
injector.map(IService).toType(SomeService)
injector.map(IService).toSingleton(SomeService)
injector.map(SomeService).asSingleton()
Faster
Local vs shared scopes
Hard vs soft mappings

7. Context & Startup
framework/readme-context.md 7

8. context = new Context()
.extend(MVCSBundle)
.configure(MyAppConfig, this);
No more extend and override
Opt-in extensions
Convenient, shareable bundles
Conventions for configuration
Consolidated startup process
framework/readme-context.md 8

9. Commands
extensions/eventCommandMap 9

10. eventCommandMap
.map(SomeEvent.EVENT, SomeEvent)
.toCommand(MyCommand)
.once();
extensions/eventCommandMap 10

11. Mediators
extensions/mediatorMap 11

12. mediatorMap
.map(SomeType)
.toMediator(SomeMediator)
Can map to interfaces and abstract types
Possibly many mediators per view
Nested stage listener optimisations
extensions/mediatorMap 12

13. Configs
framework/readme-context.md 13

14. context = new Context()
.extend(MVCSBundle)
.configure(MyAppConfig, this);
framework/readme-context.md 14

15. class ViewConfig
{
public function ViewConfig(mediatorMap:IMediatorMap)
{
mediatorMap.map(SomeView)
.toMediator(SomeMediator);
}
}
framework/readme-context.md 15

16. class MyModuleConfig implements IConfig
{
[Inject]
public var mediatorMap:IMediatorMap;
public function configure():void
{
mediatorMap.map(SomeView)
.toMediator(SomeMediator);
}
}
framework/readme-context.md 16

17. Extensions
extensions 17

18. public class EventCommandMapExtension
implements IExtension
{
public function extend(context:IContext):void
{
context.injector
.map(IEventCommandMap)
.toSingleton(EventCommandMap);
}
}
extensions/eventCommandMap 18

19. Extensions are installed immediately:
context.extend(MyExtension)
~=
new MyExtension().extend(context)
extensions 19

20. Bundles
bundles 20

21. context = new Context()
.extend(MVCSBundle)
.configure(MyAppConfig, this);
bundles 21

22. public class MVCSBundle implements IBundle
{
public function extend(context:IContext):void
{
context.extend(
ModularityExtension,
EventCommandMapExtension,
... etc ...
MediatorMapExtension,
StageSyncExtension);
context.configure(ContextViewListenerConfig);
}
}
bundles/mvcs 22

23. Bundles are installed immediately:
context.extend(MyBundle)
~=
new MyBundle().extend(context)
bundles 23

24. Bundles vs Extensions
extensions 24

25. An extension integrates a single utility or library with a
Robotlegs context
A bundle installs a selection of extensions and
configurations into a Robotlegs context
extensions 25

26. Logging
framework/readme-logging.md 26

27. Lightweight logging system built in: context.getLogger(MyClass)
Optional logging extensions
LoggingExtension: allows you to [Inject] public var logger:ILogger;
InjectorLoggingExtension: logs injection events (not 4 production!)
TraceLoggingExtension: simple trace log target
extensions/logging 27
