Annotation Interface Mutator

@Retention(CLASS) @Target(TYPE) public @interface Mutator

Used in conjunction with @Bean to declare a mutating socket bean.

A mutating socket bean must implement Function<A, B> where A is the type of the socket exposed by the module and B is the type of the instance after transformation and used during dependency injection. 


 @Mutator @Bean
 public class MutatingSocketBean implements Function<Type, TransformedType> {
 
     @Override
     public TransformedType apply(Type instance) {...}
 }

Such socket can be created when there is a need to pre-process, adapt, decorate or transform an external dependency to fit module's needs.
