As I explained in this post, the framework provides a set of installers for registering components against interfaces in the container.
Another powerful tool in the composition framework is the
ContentFactory. This provides methods for registering and getting content based on a
contentType string. When getting content, if the
contentType is not found in the container, it will try to fallback using substrings of
contentType by progressively removing sections after a
As an example, we might have some serializers that inherit from
We can create a new
SerializerFactory that inherits from
Then we use a custom installer to register the factory as a singleton, and also to register our default content (i.e. the serializers).
We are now able to use the
SerializerFactory.GetContentFor(string contentType) method to retrieve our serializers by the name we registered them with:
SerializerFactory.GetContentFor("Foo.Bar.Baz")will fallback to contentType of “Foo.Bar” and return
In the next post I’ll show you how to get set up with endjin composition framework in an MVC4 / WebAPI application.
