TyphoonAssemblyActivator

[jasperblues]

Users can still use this class if they wish. However:

Drivers

• TyphoonComponentFactory is an extra concept that needs to be learned and read in the documentation. This doesn't need to be the case.
• TyphoonComponentFactory being public API increases cost + overhead in maintaining the docs. Especially as we now have Swift version and ObjC version.
• Casting between factory and assembly does not work in Swift.

Implementation:

Add the following to Typhoon assembly:

/*
* Returns NO. Facade to the TyphoonComponentFactory method (which returns YES). 
*/
@property(nonatomic, readonly) BOOL isBuilt; 

/**
* Raises 'not built' exception. Facade to the TyphoonComponentFactory method 
*/
- (id) componentForType:(id)classOrProtocol; 

Create the following class:

@interface TyphoonAssemblyActivator

@property(nonatomic, copy, readonly) NSArray *assemblies; 

- (instancetype) initWithAssemblies:(NSArray *)assemblies; 

- (void) build;

@end

The build method will cause the array of non-built assemblies to be replaced with built assemblies.

• Before using TyphoonAssemblyActivator, TyphoonAssembly returns TyphonDefinitions (recipes to build instnaces).
• After using TyphoonAssemblyActivator, the assembly returns actual built instances.
• Everything with TyphoonComponentFactory happens behind the scenes.
• No issues with casting in Swift.
