New initializer injection TyphoonParameterInjectedByFactoryReference

[jasperblues]

. . to match the recent addition to property-style injectors.

Any comments @alexgarbarev ?

No, it's clear.

And I think we have to do same API with boxing primitives for initializer. But now I see that it cannot be done by KVC, and I have to implement same way as KVC (with unboxing) but for initializer invocation.

FactoryReference way also should be introduced in xml, I believe.

Also I want to add void* pointer injection. It will be useful to inject dispatch_queue_t for example. We have to parse ^void type at runtime and add to typeDescription

👍 It would be great to give initializer the same treatment.

Take a look at TyphoonTypeDescriptor, I believe it can decode void* arguments . . . (though it hasn't been used directly for this purpose yet).

For void*, both these conditions must be true

• descriptor.primitiveType == TyphoonPrimitiveTypeVoid
• descriptor.isPointer == YES

A point that is not directly related, but interesting:

As you've probably observed, the objective-C runtime gives very good introspection for properties. . . But for selector arguments its not quite as good, its either the primitive type or simply 'id'. . . this is why Typhoon's auto-wiring macros and by-type injection is only available for properties. . . for initializer it has to be manually specified. . . Primitive introspection is there though. . .

If anyone wants to take this issue, just assign it to yourself. Otherwise I'll take it in the next few days.

This issue waits until #162 resolved (because depends on)

[jasperblues]

Issue #162 is implemented and can be closed after review.
