ClassDescriptionDeserializer only used for abstract types used as placeholders during polymorphic type handling deserialization.Abstract factory base class that can provide deserializers for standard JDK classes, including collection classes and simple heuristics for "upcasting" common collection interface types (such as
Collection).Deserializer class that can deserialize instances of arbitrary bean objects, usually from JSON Object structs,Base class forBeanDeserializer.Builder class used for aggregating deserialization information about a POJO, in order to build aJsonDeserializerfor deserializing instances.Concrete deserializer factory class that adds full Bean deserializer construction logic using class introspection.Abstract class that defines API for objects that can be registered to participate in constructingJsonDeserializerinstances (viaDeserializerFactory).Class that handles deserialization using a separate Builder class, which is used for data binding and produces actual deserialized value at the end of data binding.Add-on interface thatJsonDeserializers can implement to get a callback that can be used to create contextual (context-dependent) instances of deserializer to use for handling properties of supported type.Add-on interface thatKeyDeserializers can implement to get a callback that can be used to create contextual instances of key deserializer to use for handling Map keys of supported type.This concrete sub-class implements property that is passed via Creator (constructor or static factory method).Alternative toDataFormatDetectorthat needs to be used when using data-binding.Result class, similar toDataFormatMatcherCompleteDeserializationContextimplementation that adds extended API forObjectMapper(andObjectReader) to call, as well as implements certain parts that base class has left abstract.Actual full concrete implementationThis is the class that can be registered (viaDeserializationConfigobject owner byObjectMapper) to get called when a potentially recoverable problem is encountered during deserialization process.Class that defines caching layer between callers (likeObjectMapper,DeserializationContext) and classes that construct deserializers (DeserializerFactory).Abstract class that defines API used byDeserializationContextto construct actualJsonDeserializerinstances (which are then cached by context and/or dedicated cache).Interface that defines API for simple extensions that can provide additional deserializers for various types.BasicDeserializersimplementation that implements all methods but provides no deserializers.Interface that defines API for simple extensions that can provide additional deserializers for deserializer Map keys of various types, from JSON property names.Helper interface implemented by classes that are to be used as null providers during deserialization.Interface used to indicate deserializers that want to do post-processing after construction but before being returned to caller (and possibly cached) and used.Class that represents a "wildcard" set method which can be used to generically set values of otherwise unmapped (aka "unknown") properties read from JSON content.Base class for deserializable properties of a bean: contains both type and name definitions, and reflection-based set functionality.Helper class that is designed to both make it easier to sub-class delegating subtypes and to reduce likelihood of breakage when new methods are added.Exception thrown during deserialization when there are object id that can't be resolved.Helper class forUnresolvedForwardReference, to contain information about unresolved ids.Class that defines simple API implemented by objects that create value instances.PartialValueInstantiatorimplementation that is strongly recommended to be used instead of directly extendingValueInstantiatoritself.DelegatingValueInstantiatorimplementation meant as a base type that by default delegates methods to specified fallback instantiator.Interface for providers ofValueInstantiatorinstances.Basic "NOP" implementation that can be used as the base class for custom implementations.
