@ConsumerType public interface ImplementationPicker
With using the @Model.adapters attribute it is possible to define interfaces or super classes to which the model implementation is an adaption target. It is possible that multiple models implement the same type.
In this case services implementing the
ImplementationPicker interface are
queried to decide which implementation should be chosen. If multiple implementations
of this interface exists they are queried one after another by service ranking.
The first that picks an implementation is the winner.
