Protected static AnnotationIntrospector DEFAULT_ANNOTATION_INTROSPECTOR Protected TypeFactory _typeFactory - Specific factory used for creating JavaType instances needed to allow modules to add more custom type handling (mostly to support types of non-Java JVM languages). Protected SubtypeResolver _subtypeResolver - Thing used for registering sub-types, resolving them to super/sub-types as needed. Protected DefaultSerializerProvider _serializerProvider - Object that manages access to serializers used for serialization, including caching. Protected SerializerFactory _serializerFactory - Serializer factory used for constructing serializers. Protected SerializationConfig _serializationConfig - Configuration object that defines basic global settings for the serialization process. Protected ConcurrentHashMap> _rootDeserializers - We will use a separate main-level Map for keeping track of root-level deserializers.
#Jackson objectmapper with list within a list with json filr registration
Protected Set _registeredModuleTypes - Set of module types (as per Module.getTypeId() that have been registered kept track of iff MapperFeature.IGNORE_DUPLICATE_MODULE_REGISTRATIONS is enabled, so that duplicate registration calls can be ignored (to avoid adding same handlers multiple times, mostly). Protected ConfigOverrides _propertyOverrides - Currently active per-type configuration overrides, accessed by declared type of property.

Protected SimpleMixInResolver _mixIns - Mapping that defines how to apply mix-in annotations: key is the type to received additional annotations, and value is the type that has annotations to "mix in". Protected JsonFactory _jsonFactory - Factory used to create JsonParser and JsonGenerator instances as necessary. Protected InjectableValues _injectableValues - Provider for values to inject in deserialized POJOs. Protected DefaultDeserializationContext _deserializationContext - Blueprint context object stored here to allow custom sub-classes. Protected DeserializationConfig _deserializationConfig - Configuration object that defines basic global settings for the serialization process.

Static class ObjectMapper.DefaultTypeResolverBuilderĬustomized TypeResolverBuilder that provides type resolver builders used with so-called "default typing" (see enableDefaultTyping() for details).Įnumeration used with enableDefaultTyping() to specify what kind of types (classes) default typing should be used for. Class Declarationįollowing is the declaration for .ObjectMapper class − ObjectMapper also acts as a factory for more advanced ObjectReader and ObjectWriter classes.

It is also highly customizable to work both with different styles of JSON content, and to support more advanced Object concepts such as polymorphism and Object identity. ObjectMapper class ObjectMapper provides functionality for reading and writing JSON, either to and from basic POJOs (Plain Old Java Objects), or to and from a general-purpose JSON Tree Model (JsonNode), as well as related functionality for performing conversions. ObjectMapper is the main actor class of Jackson library.
