possible GetObjectsOfType replacement

Question

I have this small piece of code

var idObjects = Spring.Context.Support.ContextRegistry.GetContext()
                      .GetObjectsOfType(typeof (ICustomIn

You could also use method injection:

In sharedLib:

public class MyService
{
    public void ProcessAll()
    {
      foreach (ICustomInterfaceThatDoesSomething icitds in GetAllImplementers())
        icitds.DoSomething();
    }

    protected virtual IEnumerable GetAllImplementers()
    {
      // note that the Spring dependency is gone
      // you can also make this method abstract, 
      // or create a more useful default implementation
      return new List(); 
    }
}

In the web app add a class that implements GetAllImplementers():

public class ServiceLocatorImplementer : IMethodReplacer
{
    protected IEnumerable GetAllImplementers()
    {
        var idObjects = Spring.Context.Support.ContextRegistry.GetContext()
            .GetObjectsOfType(typeof(ICustomInterfaceThatDoesSomething));

        return idObjects.Values.Cast();
    }

    public object Implement(object target, MethodInfo method, object[] arguments)
    {
        return GetAllImplementers();
    }
}

And configure method injection in you web app's object definitions:
