java.lang.Object

com.fasterxml.jackson.databind.introspect.ClassIntrospector

Direct Known Subclasses:

BasicClassIntrospector

public abstract class ClassIntrospector
extends Object

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.

Methods

Modifier and Type	Method and Description
abstract BeanDescription	forClassAnnotations(MapperConfig<?> cfg, JavaType type, ClassIntrospector.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.
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
abstract BeanDescription	forDeserialization(DeserializationConfig cfg, JavaType type, ClassIntrospector.MixInResolver r) Factory method that constructs an introspector that has all information needed for deserialization purposes.
abstract BeanDescription	forDeserializationWithBuilder(DeserializationConfig cfg, JavaType type, ClassIntrospector.MixInResolver r) Factory method that constructs an introspector that has all information needed for constructing deserializers that use intermediate Builder objects.
abstract BeanDescription	forDirectClassAnnotations(MapperConfig<?> cfg, JavaType type, ClassIntrospector.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.
abstract BeanDescription	forSerialization(SerializationConfig cfg, JavaType type, ClassIntrospector.MixInResolver r) Factory method that constructs an introspector that has all information needed for serialization purposes.
