Class Summary

Class	Description
JsonFormat.Value	Helper class used to contain information from a single JsonFormat annotation.
JsonTypeInfo.None	This marker class that is only to be used with defaultImpl annotation property, to indicate that there is no default implementation specified.
ObjectIdGenerator<T>	Definition of API used for constructing Object Identifiers (as annotated using JsonIdentityInfo).
ObjectIdGenerator.IdKey	Simple key class that can be used as a key for ObjectId-to-POJO mappings, when multiple ObjectId types and scopes are used.
ObjectIdGenerators	Container class for standard ObjectIdGenerator implementations.
ObjectIdGenerators.IntSequenceGenerator	Simple sequence-number based generator, which uses basic Java ints (starting with value 1) as Object Identifiers.
ObjectIdGenerators.None	Abstract marker class used to allow explicitly specifying that no generator is used; which also implies that no Object Id is to be included or used.
ObjectIdGenerators.PropertyGenerator	Abstract place-holder class which is used to denote case where Object Identifier to use comes from a POJO property (getter method or field).
ObjectIdGenerators.UUIDGenerator	Implementation that just uses UUIDs as reliably unique identifiers: downside is that resulting String is 36 characters long.

Enum Summary

Enum	Description
JsonAutoDetect.Visibility	Enumeration for possible visibility thresholds (minimum visibility) that can be used to limit which methods (and fields) are auto-detected.
JsonFormat.Shape	Value enumeration used for indicating preferred Shape; translates loosely to JSON types, with some extra values to indicate less precise choices (i.e.
JsonInclude.Include	Enumeration used with JsonInclude to define which properties of Java Beans are to be included in serialization.
JsonTypeInfo.As	Definition of standard type inclusion mechanisms for type metadata.
JsonTypeInfo.Id	Definition of different type identifiers that can be included in JSON during serialization, and used for deserialization.
PropertyAccessor	Enumeration used to define kinds of elements (called "property accessors") that annotations like JsonAutoDetect apply to.

Annotation Types Summary

Annotation Type	Description
JacksonAnnotation	Meta-annotation (annotations used on other annotations) used for marking all annotations that are part of Jackson package.
JacksonAnnotationsInside	Meta-annotation (annotations used on other annotations) used for indicating that instead of using target annotation (annotation annotated with this annotation), Jackson should use meta-annotations it has.
JacksonInject	Jackson-specific annotation used for indicating that value of annotated property will be "injected", i.e.
JsonAnyGetter	Marker annotation that can be used to define a non-static, no-argument method or member field as something of a reverse of JsonAnySetter method; basically being used like a getter but such that contents of the returned Map (type must be Map) are serialized as if they were actual properties of the bean that contains method/field with this annotations.
JsonAnySetter	Marker annotation that can be used to define a non-static, two-argument method (first argument name of property, second value to set), to be used as a "fallback" handler for all otherwise unrecognized properties found from JSON content.
JsonAutoDetect	Class annotation that can be used to define which kinds of Methods are to be detected by auto-detection.
JsonBackReference	Annotation used to indicate that associated property is part of two-way linkage between fields; and that its role is "child" (or "back") link.
JsonCreator	Marker annotation that can be used to define constructors and factory methods as one to use for instantiating new instances of the associated class.
JsonFilter	Annotation used to indicate which logical filter is to be used for filtering out properties of type (class) annotated; association made by this annotation declaring ids of filters, and com.fasterxml.jackson.databind.ObjectMapper (or objects it delegates to) providing matching filters by id.
JsonFormat	General-purpose annotation used for configuring details of how values of properties are to be serialized.
JsonGetter	Marker annotation that can be used to define a non-static, no-argument value-returning (non-void) method to be used as a "getter" for a logical property.
JsonIdentityInfo	Annotation used for indicating that values of annotated type or property should be serializing so that instances either contain additional object identifier (in addition actual object properties), or as a reference that consists of an object id that refers to a full serialization.
JsonIdentityReference	Optional annotation that can be used for customizing details of a reference to Objects for which "Object Identity" is enabled (see JsonIdentityInfo).
JsonIgnore	Marker annotation that indicates that the annotated method or field is to be ignored by introspection-based serialization and deserialization functionality.
JsonIgnoreProperties	Annotation that can be used to either suppress serialization of properties (during serialization), or ignore processing of JSON properties read (during deserialization).
JsonIgnoreType	Marker annotation that indicates that all properties of annotated type are to be ignored during serialization and deserialization.
JsonInclude	Annotation used to indicate when value of the annotated property (when used for a field, method or constructor parameter), or all properties of the annotated class, is to be serialized.
JsonManagedReference	Annotation used to indicate that annotated property is part of two-way linkage between fields; and that its role is "parent" (or "forward") link.
JsonProperty	Marker annotation that can be used to define a non-static method as a "setter" or "getter" for a logical property (depending on its signature), or non-static object field to be used (serialized, deserialized) as a logical property.
JsonPropertyOrder	Annotation that can be used to define ordering (possibly partial) to use when serializing object properties.
JsonRawValue	Marker annotation that indicates that the annotated method or field should be serialized by including literal String value of the property as is, without quoting of characters.
JsonRootName	Annotation similar to XmlRootElement, used to indicate name to use for root-level wrapping, if wrapping is enabled.
JsonSetter	Marker annotation that can be used to define a non-static, single-argument method to be used as a "setter" for a logical property as an alternative to recommended JsonProperty annotation (which was introduced in version 1.1).
JsonSubTypes	Annotation used with JsonTypeInfo to indicate sub types of serializable polymorphic types, and to associate logical names used within JSON content (which is more portable than using physical Java class names).
JsonSubTypes.Type	Definition of a subtype, along with optional name.
JsonTypeId	Marker annotation that can be used on a property accessor (field, getter or setter, constructor parameter) to indicate that the property is to contain type id to use when including polymorphic type information.
JsonTypeInfo	Annotation used for configuring details of if and how type information is used with JSON serialization and deserialization, to preserve information about actual class of Object instances.
JsonTypeName	Annotation used for binding logical name that the annotated class has.
JsonUnwrapped	Annotation used to indicate that a property should be serialized "unwrapped"; that is, if it would be serialized as JSON Object, its properties are instead included as properties of its containing Object.
JsonValue	Marker annotation similar to XmlValue that indicates that results of the annotated "getter" method (which means signature must be that of getters; non-void return type, no args) is to be used as the single value to serialize for the instance.
JsonView	Annotation used for indicating view(s) that the property that is defined by method or field annotated is part of.

Package com.fasterxml.jackson.annotation Description

Public core annotations, most of which are used to configure how Data Mapping/Binding works. Annotations in this package can only have dependencies to non-annotation classes in Core package; annotations that have dependencies to Mapper classes are included in Mapper module (under org.codehaus.jackson.map.annotate). Also contains parameter types (mostly enums) needed by annotations.

Note that prior versions (1.x) contained these annotations within 'core' jar, as part of Streaming API.
