>          Components: jclouds-core
>    Affects Versions: 1.8.0

> Currently, the {{@Delegate}} annotation can only delegate to a single API and there is a need to support multiple levels of delegation.
> For example, a {{TopLevelApi}} needs to delegate to a {{FeatureApi}}, that in turn delegates to a {{SubFeatureApi}}:
> {code:java}
> public interface TopLevelApi {
>     @Delegate
>     FeatureApi getFeatureApi();
> }
> public interface FeatureApi {
>     @Delegate 
>     SubFeatureApi getSubFeatureApi();
> }
> public interface SubFeatureApi {
>     // subfeature specific APIs
>     String doSomething();
> }
> {code}
> {{HttpApiModule}} uses {{BinderUtils.bindHttpApi}} to bind a top level API which can only delegate one level deep at this time.
