# Package org.codehaus.jackson.map.introspect

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

See: Description

- Interface Summary
  Interface | Description
  --- | ---
  MethodFilter | Simple interface that defines API used to filter out irrelevant methods
  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.

- 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 `AnnotatedMethod`s, 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.
  AnnotationMap | Simple helper class used to keep track of collection of Jackson Annotations associated with annotatable things (methods, constructors, classes).
  BasicBeanDescription | Default `BeanDescription` implementation.
  BasicClassIntrospector |
  BasicClassIntrospector.GetterMethodFilter | Deprecated Since 1.9 just don't use
  BasicClassIntrospector.SetterAndGetterMethodFilter | Deprecated Since 1.9 just don't use
  BasicClassIntrospector.SetterMethodFilter | Deprecated Since 1.9 just don't use
  JacksonAnnotationIntrospector | `AnnotationIntrospector` implementation that handles standard Jackson annotations.
  MemberKey | Helper class needed to be able to efficiently access class member functions (`Method`s and `Constructor`s) in `Map`s.
  NopAnnotationIntrospector | Dummy, "no-operation" implementation of `AnnotationIntrospector`.
  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.
  VisibilityChecker.Std | Default standard implementation is purely based on visibility modifier of given class members, and its configured minimum levels.

## Package org.codehaus.jackson.map.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.
