Package com.fasterxml.jackson.databind.deser.impl

package com.fasterxml.jackson.databind.deser.impl

Contains those implementation classes of deserialization part of data binding that are not considered part of public or semi-public interfaces. Use of these classes by non-core classes is discouraged, although occasionally this may be necessary. Note that backwards-compatibility of these classes is not guaranteed between minor releases (but is between patch releases).

Classes

Class	Description
BeanAsArrayBuilderDeserializer
BeanAsArrayDeserializer	Variant of BeanDeserializer used for handling deserialization of POJOs when serialized as JSON Arrays, instead of JSON Objects.
BeanPropertyMap	Helper class used for storing mapping from property name to SettableBeanProperty instances.
CreatorCandidate
CreatorCandidate.Param
CreatorCollector	Container class for storing information on creators (based on annotations, visibility), to be able to build actual ValueInstantiator later on.
ErrorThrowingDeserializer	A deserializer that stores an Error caught during constructing of the deserializer, which needs to be deferred and only during actual attempt to deserialize a value of given type.
ExternalTypeHandler	Helper class that is used to flatten JSON structure when using "external type id" (see JsonTypeInfo.As.EXTERNAL_PROPERTY).
ExternalTypeHandler.Builder
FailingDeserializer	Special bogus "serializer" that will throw MismatchedInputException if an attempt is made to deserialize a value.
FieldProperty	This concrete sub-class implements property that is set directly assigning to a Field.
InnerClassProperty	This sub-class is used to handle special case of value being a non-static inner class.
JavaUtilCollectionsDeserializers	Helper class used to contain logic for deserializing "special" containers from java.util.Collections and java.util.Arrays.
JDKValueInstantiators	Container for a set of ValueInstantiators used for certain critical JDK value types, either as performance optimization for initialization time observed by profiling, or due to difficulty in otherwise finding constructors.
ManagedReferenceProperty	Wrapper property that is used to handle managed (forward) properties Basically just needs to delegate first to actual forward property, and then to back property.
MergingSettableBeanProperty	SettableBeanProperty implementation that will try to access value of the property first, and if non-null value found, pass that for update (using JsonDeserializer.deserialize(com.fasterxml.jackson.core.JsonParser, com.fasterxml.jackson.databind.DeserializationContext, Object)) instead of constructing a new value.
MethodProperty	This concrete sub-class implements property that is set using regular "setter" method.
NullsAsEmptyProvider	Simple NullValueProvider that will return "empty value" specified by JsonDeserializer provider is constructed with.
NullsConstantProvider	Simple NullValueProvider that will simply return given constant value when a null is encountered; or, with a specially constructed instance (see NullsConstantProvider.skipper(), indicate the need for special behavior of skipping property altogether (not setting as anything OR throwing exception).
NullsFailProvider	Simple NullValueProvider that will always throw a InvalidNullException when a null is encountered.
ObjectIdReader	Object that knows how to deserialize Object Ids.
ObjectIdReferenceProperty
ObjectIdReferenceProperty.PropertyReferring
ObjectIdValueProperty	Specialized SettableBeanProperty implementation used for virtual property that represents Object Id that is used for some POJO types (or properties).
PropertyBasedCreator	Object that is used to collect arguments for non-default creator (non-default-constructor, or argument-taking factory method) before creator can be called.
PropertyBasedObjectIdGenerator
PropertyValue	Base class for property values that need to be buffered during deserialization.
PropertyValueBuffer	Simple container used for temporarily buffering a set of PropertyValues.
ReadableObjectId	Simple value container for containing information about single Object Id during deserialization
ReadableObjectId.Referring
SetterlessProperty	This concrete sub-class implements Collection or Map property that is indirectly by getting the property value and directly modifying it.
TypeWrappedDeserializer	Simple deserializer that will call configured type deserializer, passing in configured data deserializer, and exposing it all as a simple deserializer.
UnsupportedTypeDeserializer	Special bogus "serializer" that will throw MismatchedInputException if an attempt is made to deserialize a value.
UnwrappedPropertyHandler	Object that is responsible for handling acrobatics related to deserializing "unwrapped" values; sets of properties that are embedded (inlined) as properties of parent JSON object.
ValueInjector	Class that encapsulates details of value injection that occurs before deserialization of a POJO.
