Lazy Func<T>

[shapper]

Hello,

I have the following:

public class Foo {
private readonly Func<IPostService> _postServiceFactory;
public Foo(Func<IPostService> postServiceFactory) {
}
}

IPostService implements IService.

How can I set the Func<T> in Structure Map for all types of IService?

I think this is called Lazy Func<T> but I have been trying a few
options but it never compiles.

Thanks,
Miguel

I am not sure there is an easy way to do this. You may have to create your own scanner if you have a lot of them, but I think this should work:

 

For<Func<IPostService>>().Use(() => /* Your func here */);

Yes, I tried exactly that:

For<Func<IPostService>>().Use(() =>

ObjectFactory.GetInstance<PostService>());

Basically, I am checking the Structure Map Lazy Func<T> to deliver the
current PostService instance in use.

However, on the Foo class that Func is null.

What am I doing wrong?

Thank You,
Miguel

For<Func<IPostService>>().Use(() => the actual function)

Also, don't use ObjectFactory in your Use method... use Use( container => container.SomeMethod)

Better still, just register your T and Func<T> will work automatically if you're on 2.6+.

Thanks boss man!

it'll just use the greediest ctor?

[Jeremy D. Miller]

It just delegates to whatever is registered for the T, so yes.

Ctor selection will get more flexible in 3.0 -- whenever that happens;)
