Direct Known Subclasses:

BasicClassIntrospector

public abstract class ClassIntrospector
extends java.lang.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.

static interface	ClassIntrospector.MixInResolver	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)
