How do I tell Windsor to add an Interceptor to all components registered that implement IMustBeIntercepted

Question

If I registered several components with Windsor.

IAnimal provides BigAnimal IPerson provides SmellyPerson IWhale provides BlueWhale

etc.. pretty standard com

Answer 1

Simply create an interface like this:

public interface IMustBeIntercepted {}

and a facility like this:

public class InterceptionFacility : AbstractFacility {
    protected override void Init() {
        Kernel.ComponentRegistered += new Castle.MicroKernel.ComponentDataDelegate(Kernel_ComponentRegistered);
    }

    void Kernel_ComponentRegistered(string key, Castle.MicroKernel.IHandler handler) {
        if(typeof(IMustBeIntercepted).IsAssignableFrom(handler.ComponentModel.Implementation)) {
            handler.ComponentModel.Interceptors.Add(new InterceptorReference(typeof(TestInterceptor)));
        }
    }
}

Then register the facility to the container using the tag. Now all components that implements IMustBeIntercepted will be intercepted by the interceptor TestInterceptor.
