Interface used for decoupling details of how mix-in annotation definitions are accessed (via this interface), and how they are stored (defined by classes that implement the interface)

Method that will check if there are "mix-in" classes (with mix-in annotations) for given class

Factory method that constructs an introspector that has all information needed for deserialization purposes.
    		JavaType typeMixInResolver r);

    
Factory method that constructs an introspector that has all information needed for constructing deserializers that use intermediate Builder objects.

Factory method that constructs an introspector that has information necessary for creating instances of given class ("creator"), as well as class annotations, but no information on member methods
    public abstract BeanDescription forCreation(DeserializationConfig cfgJavaType type,
            MixInResolver r);

    
Factory method that constructs an introspector that only has information regarding annotations class itself (or its supertypes) has, but nothing on methods or constructors.
    public abstract BeanDescription forClassAnnotations(MapperConfig<?> cfgJavaType type,
            MixInResolver r);

    
Factory method that constructs an introspector that only has information regarding annotations class itself has (but NOT including its supertypes), but nothing on methods or constructors.
