Package com.fasterxml.jackson.databind.introspect

Functionality needed for Bean introspection, required for detecting accessors and mutators for Beans, as well as locating and handling method annotations.

Interface Summary

Interface	Description
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)
TypeResolutionContext	Interface that defines API used by members (like AnnotatedMethod) to dynamically resolve types they have.
VisibilityChecker<T extends VisibilityChecker<T>>	Interface for object used for determine which property elements (methods, fields, constructors) can be auto-detected, with respect to their visibility modifiers.
WithMember<T>

Class Summary

Class	Description
Annotated	Shared base class used for anything on which annotations (included within a AnnotationMap).
AnnotatedClass
AnnotatedConstructor
AnnotatedField	Object that represents non-static (and usually non-transient/volatile) fields of a class.
AnnotatedMember	Intermediate base class for annotated entities that are members of a class; fields, methods and constructors.
AnnotatedMethod
AnnotatedMethodMap	Simple helper class used to keep track of collection of AnnotatedMethods, accessible by lookup.
AnnotatedParameter	Object that represents method parameters, mostly so that associated annotations can be processed conveniently.
AnnotatedWithParams	Intermediate base class that encapsulates features that constructors and methods share.
AnnotationIntrospectorPair	Helper class that allows using 2 introspectors such that one introspector acts as the primary one to use; and second one as a fallback used if the primary does not provide conclusive or useful result for a method.
AnnotationMap	Simple helper class used to keep track of collection of Jackson Annotations associated with annotatable things (methods, constructors, classes).
BasicBeanDescription	Default BeanDescription implementation used by Jackson.
BasicClassIntrospector
BeanPropertyDefinition	Simple value classes that contain definitions of properties, used during introspection of properties to use for serialization and deserialization purposes.
ClassIntrospector	Helper class used to introspect features of POJO value classes used with Jackson.
ConcreteBeanPropertyBase	Intermediate BeanProperty class shared by concrete readable- and writable property implementations for sharing common functionality.
JacksonAnnotationIntrospector	AnnotationIntrospector implementation that handles standard Jackson annotations.
MemberKey	Helper class needed to be able to efficiently access class member functions (Methods and Constructors) in Maps.
NopAnnotationIntrospector	Dummy, "no-operation" implementation of AnnotationIntrospector.
ObjectIdInfo	Container object that encapsulates information usually derived from JsonIdentityInfo annotation or its custom alternatives
POJOPropertiesCollector	Helper class used for aggregating information about all possible properties of a POJO.
POJOPropertyBuilder	Helper class used for aggregating information about a single potential POJO property.
POJOPropertyBuilder.Linked<T>	Node used for creating simple linked lists to efficiently store small sets of things.
POJOPropertyBuilder.MemberIterator<T extends AnnotatedMember>
SimpleMixInResolver	Simple implementation of ClassIntrospector.MixInResolver that just uses a Map for containing mapping from target to mix-in classes.
TypeResolutionContext.Basic
VirtualAnnotatedMember	Placeholder used by virtual properties as placeholder for underlying AnnotatedMember.
VisibilityChecker.Std	Default standard implementation is purely based on visibility modifier of given class members, and its configured minimum levels.

Package com.fasterxml.jackson.databind.introspect Description

Functionality needed for Bean introspection, required for detecting accessors and mutators for Beans, as well as locating and handling method annotations.

Beyond collecting annotations, additional "method annotation inheritance" is also supported: whereas regular JDK classes do not add annotations from overridden methods in any situation. But code in this package does. Similarly class-annotations are inherited properly from interfaces, in addition to abstract and concrete classes.
