# Package com.fasterxml.jackson.databind.jsontype

Package that contains interfaces that define how to implement functionality for dynamically resolving type during deserialization.

See: Description

- Interface Summary
  Interface | Description
  --- | ---
  TypeIdResolver | Interface that defines standard API for converting types to type identifiers and vice versa.
  TypeResolverBuilder<T extends TypeResolverBuilder<T>> | Interface that defines builders that are configured based on annotations (like `JsonTypeInfo` or JAXB annotations), and produce type serializers and deserializers used for handling type information embedded in JSON to allow for safe polymorphic type handling.

- Class Summary
  Class | Description
  --- | ---
  NamedType | Simple container class for types with optional logical name, used as external identifier
  SubtypeResolver | Helper object used for handling registration on resolving of super-types to sub-types.
  TypeDeserializer | Interface for deserializing type information from JSON content, to type-safely deserialize data into correct polymorphic instance (when type inclusion has been enabled for type handled).
  TypeSerializer | Interface for serializing type information regarding instances of specified base type (super class), so that exact subtype can be properly deserialized later on.

## Package com.fasterxml.jackson.databind.jsontype Description

Package that contains interfaces that define how to implement functionality for dynamically resolving type during deserialization. This is needed for complete handling of polymorphic types, where actual type can not be determined statically (declared type is a supertype of actual polymorphic serialized types).
