Helper class used to introspect features of POJO value classes used with Jackson. The main use is for finding out POJO construction (creator) and value access (getters, setters) methods and annotations that define configuration of using those methods.

public abstract BeanDescription
forClassAnnotations(MapperConfig<?> cfg, JavaType type, ClassIntrospector.MixInResolver r)

public abstract BeanDescription
forCreation(DeserializationConfig cfg, JavaType type, ClassIntrospector.MixInResolver r)

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
forDeserialization(DeserializationConfig cfg, JavaType type, ClassIntrospector.MixInResolver r)

Factory method that constructs an introspector that has all information needed for deserialization purposes.

public abstract BeanDescription
forDeserializationWithBuilder(DeserializationConfig cfg, JavaType builderType, ClassIntrospector.MixInResolver r, BeanDescription valueTypeDesc)

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

Method Summary

Modifier and TypeMethod and Description
public ClassIntrospector.MixInResolver
copy()

Method called to create a new, non-shared copy, to be used by different ObjectMapper instance, and one that should not be connected to this instance, if resolver has mutable state.

findMixInClassFor(Class<?> cls)

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