How to perform conditional binding in StructureMap from within a registry and without the use of generics?

Question

I am familiar with Ninject and in Ninject you can do something similar to

Bind<ICalendar>().To<MonthCalendar>().WhenInjectedInto(typeof(Roster)).InRequestScope();

I'm not sure how to perform something similar in StructureMap. I need to be able to do this dynamically from my own binding without the use of the generic StructureMap methods. Additionally, I need to be able to do it from inside a Registry class. For example...

For(binding.Source).LifecycleIs(GetLifecycle(binding.Scope)).Use(binding.Destination);

I have looked at stack overflow and codebetter for ideas but can not work out how to do conditional binding as in the aforementioned Ninject example.

Answer 1

If I interpret your Ninject configuration correctly - the generic solution in structure map would be:

For<Roster>().HttpContextScoped().Use<Roster>()
  .Ctor<ICalendar>().Is<MonthCalendar>();

Edit:

For doing the same thing with fully dynamic registrations instead you should be able to use this:

For(binding.Source).LifecycleIs(binding.Lifecycle)
  .Use(binding.Destination).Child(binding.ChildSource)
  .IsConcreteType(binding.ChildDestination);

For configuring a type registration dynamically you could use a convention:

public class DynamicConvention : IRegistrationConvention
{
        public void Process(Type type, Registry registry)
        {
            TypeRegistrationSettings typeSettings = FindTypeSettings(type);
            if (typeSettings == null)
                return;

            registry.For(typeSettings.Source)
              .LifecycleIs(typeSettings.Lifecycle).Use(typeSettings.Destination);
        }
}

Where FindTypeSettings(type) would look up your own bindings.

The convention is registered with a scan:

ObjectFactory.Initialize(
                c => 
                    c.Scan(s => {
                        s.TheCallingAssembly();
                        s.Convention<DynamicConvention>();
                    })
                );
