Package com.fasterxml.jackson.databind.deser

Contains implementation classes of deserialization part of data binding.

Interface Summary

Interface	Description
ContextualDeserializer	Add-on interface that JsonDeserializers 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.
ContextualKeyDeserializer	Add-on interface that KeyDeserializers 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.
Deserializers	Interface that defines API for simple extensions that can provide additional deserializers for various types.
KeyDeserializers	Interface that defines API for simple extensions that can provide additional deserializers for deserializer Map keys of various types, from JSON property names.
NullValueProvider	Helper interface implemented by classes that are to be used as null providers during deserialization.
ResolvableDeserializer	Interface used to indicate deserializers that want to do post-processing after construction but before being returned to caller (and possibly cached) and used.
ValueInstantiator.Gettable
ValueInstantiators	Interface for providers of ValueInstantiator instances.

Class Summary

Class	Description
AbstractDeserializer	Deserializer only used for abstract types used as placeholders during polymorphic type handling deserialization.
BasicDeserializerFactory	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).
BeanDeserializer	Deserializer class that can deserialize instances of arbitrary bean objects, usually from JSON Object structs,
BeanDeserializerBase	Base class for BeanDeserializer.
BeanDeserializerBuilder	Builder class used for aggregating deserialization information about a POJO, in order to build a JsonDeserializer for deserializing instances.
BeanDeserializerFactory	Concrete deserializer factory class that adds full Bean deserializer construction logic using class introspection.
BeanDeserializerModifier	Abstract class that defines API for objects that can be registered to participate in constructing JsonDeserializer instances (via DeserializerFactory).
BuilderBasedDeserializer	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.
CreatorProperty	This concrete sub-class implements property that is passed via Creator (constructor or static factory method).
DataFormatReaders	Alternative to DataFormatDetector that needs to be used when using data-binding.
DataFormatReaders.Match	Result class, similar to DataFormatMatcher
DefaultDeserializationContext	Complete DeserializationContext implementation that adds extended API for ObjectMapper (and ObjectReader) to call, as well as implements certain parts that base class has left abstract.
DefaultDeserializationContext.Impl	Actual full concrete implementation
DeserializationProblemHandler	This is the class that can be registered (via DeserializationConfig object owner by ObjectMapper) to get called when a potentially recoverable problem is encountered during deserialization process.
DeserializerCache	Class that defines caching layer between callers (like ObjectMapper, DeserializationContext) and classes that construct deserializers (DeserializerFactory).
DeserializerFactory	Abstract class that defines API used by DeserializationContext to construct actual JsonDeserializer instances (which are then cached by context and/or dedicated cache).
Deserializers.Base	Basic Deserializers implementation that implements all methods but provides no deserializers.
SettableAnyProperty	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.
SettableBeanProperty	Base class for deserializable properties of a bean: contains both type and name definitions, and reflection-based set functionality.
SettableBeanProperty.Delegating	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.
UnresolvedId	Helper class for UnresolvedForwardReference, to contain information about unresolved ids.
ValueInstantiator	Class that defines simple API implemented by objects that create value instances.
ValueInstantiator.Base	Partial ValueInstantiator implementation that is strongly recommended to be used instead of directly extending ValueInstantiator itself.
ValueInstantiator.Delegating	Delegating ValueInstantiator implementation meant as a base type that by default delegates methods to specified fallback instantiator.
ValueInstantiators.Base	Basic "NOP" implementation that can be used as the base class for custom implementations.

Exception Summary

Exception	Description
UnresolvedForwardReference	Exception thrown during deserialization when there are object id that can't be resolved.
