module jackson.core

Package com.fasterxml.jackson.core.type


Contains classes needed for type introspection, mostly used by data binding functionality. Most of this functionality is needed to properly handled generic types, and to simplify and unify processing of things Jackson needs to determine how contained types (of java.util.Collection and java.util.Map classes) are to be handled.

With 2.9, an additional type (com.fasterxml.jackson.core.type.WritableTypeId) was added to help handling of type identifiers needed to support polymorphic type serialization, deserialization.

Class Summary

Modifier and TypeClass and Description
public abstract class
ResolvedType

Type abstraction that represents Java type that has been resolved (i.e. has all generic information, if any, resolved to concrete types).

public abstract class
TypeReference<T>

This generic abstract class is used for obtaining full generics type information by sub-classing; it must be converted to ResolvedType implementation (implemented by JavaType from "databind" bundle) to be used.

public class
WritableTypeId

This is a simple value class used between core streaming and higher level databinding to pass information about type ids to write.
