Hi
I've been looking for and trying to build a facility that provides the same
support as Guice's annotatedWith (
http://code.google.com/p/google-guice/wiki/BindingAnnotations) but for
Windsor.
Basically what I want is to be able to make a registrations like:
container.Register(Component.For<IFoo>().Instance(foo1));
container.Register(Component.For<IFoo>().Instance(foo2).AttributedWith(typeof(SomeAttribute)));
And then declare a type depending on IFoo:
public class Bar {
public Bar([Some]IFoo foo) {...}
}
Which would then get the foo2 instance instead of foo1 which it normally
would.
I have been unable to find something that already provides this and so far
haven't had luck enough to implement it myself, though I'll keep trying :)
I've been able to created the extension method allowing me to do the
registration and added the attribute info (using .AddAttributeDescription)
to the registration - currently it just a key/value pair containing a key
and the fully qualified name of the attribute type.
I've tried using the DependencyResolving event on the kernel but can't
figure out 1) how to get all the registered components so I can figure out
which has the attribute I'm looking for, and 2) how to replace the
dependency that has already been resolved.
Any suggestions of how to do this i welcomed, also if anyone knows how I
could support syntax like .AttributedWith<SomeAttribute>() instead of
passing the type using typeof I'd like that too.
Regards
Kim
