DependencyProvider and getInstance()

[darscan]

What is provided as the targetType to apply() when getInstance() is called manually? I have a situation where I need to use getInstance() rather than an Inject point, but the provider needs the targetType. At the moment it seems to pass the requested type.

Yep, it's the requested type. I only saw the option of passing null or
the requested type itself, both not making too much sense, really.

The only way to pass the targetType for getInstance would be to change
that method's signature. Unfortunately, I think that that's pretty
hard to understand. Implementing your own dependency provider really
is something entirely different from using the injector's default API,
don't you think?

Yeh, it's a tricky one. It cropped up while creating a provider for loggers:

https://github.com/robotlegs/robotlegs-framework/blob/4149bed1f83ef04e09d18e21c4f8ccc1420f6691/src/org/robotlegs/v2/extensions/logging/integration/LoggerProvider.as

There are some places where I need to pull out a fresh logger with getInstance() as the class I'm in doesn't get injected into. The only solutions I can think of are:

Expanding the getInstance signature:

getInstance(type, name="", targetType="")

or adding a new method:

getInstanceFor(type, name="", targetType="")

neither of which are terribly pretty :/
