Packages that use com.fasterxml.jackson.databind.deser.impl
Package | Description
--- | ---
com.fasterxml.jackson.databind | Contains basic mapper (conversion) functionality that allows for converting between regular streaming json content and Java objects (beans or Tree Model: support for both is via `ObjectMapper` class, as well as convenience methods included in `JsonParser`
com.fasterxml.jackson.databind.deser | Contains implementation classes of deserialization part of data binding.
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.
com.fasterxml.jackson.databind.deser.std | Contains public standard implementations of abstraction that Jackson uses.

Classes in com.fasterxml.jackson.databind.deser.impl used by com.fasterxml.jackson.databind
Class and Description
ObjectIdReader Object that knows how to serialize Object Ids.
ReadableObjectId Simple value container for containing information about single Object Id during deserialization.

Class and Description
BeanAsArrayBuilderDeserializer
BeanPropertyMap Helper class used for storing mapping from property name to `SettableBeanProperty` instances.
CreatorCollector Container class for storing information on creators (based on annotations, visibility), to be able to build actual instantiator later on.
ExternalTypeHandler Helper class that is used to flatten JSON structure when using "external type id" (see `JsonTypeInfo.As.EXTERNAL_PROPERTY`).
NullProvider To support [JACKSON-420] we need bit more indirection; this is used to produce artificial failure for primitives that don't accept JSON null as value.
ObjectIdReader Object that knows how to serialize Object Ids.
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.
ReadableObjectId Simple value container for containing information about single Object Id during deserialization.
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.

Class and 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.
ExternalTypeHandler Helper class that is used to flatten JSON structure when using "external type id" (see `JsonTypeInfo.As.EXTERNAL_PROPERTY`).
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.
ManagedReferenceProperty Wrapper property that is used to handle managed (forward) properties (see [JACKSON-235] for more information).
MethodProperty This concrete sub-class implements property that is set using regular "setter" method.
ObjectIdReader Object that knows how to serialize Object Ids.
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.
PropertyValue Base class for property values that need to be buffered during deserialization.
PropertyValueBuffer Simple container used for temporarily buffering a set of `PropertyValue`s.
SetterlessProperty This concrete sub-class implements Collection or Map property that is indirectly by getting the property value and directly modifying it.
