public class ObjectIdGenerators extends ObjectContainer class for standard
ObjectIdGenerators.PropertyGeneratorapplicability is limited in one case: it can only be used on polymorphic base types (ones indicated using
JsonTypeInfoor default typing) via class annotations: property annotation will fail due to lack of access to property, needed to determine type of Object Id for deserialization. This limitation may be lifted in future versions but it is the limitation at least up to and including Jackson 2.9.
Nested Class Summary
Nested Classes Modifier and Type Class Description
ObjectIdGenerators.IntSequenceGeneratorSimple sequence-number based generator, which uses basic Java
ints (starting with value 1) as Object Identifiers.
ObjectIdGenerators.NoneAbstract marker class used to allow explicitly specifying that no generator is used; which also implies that no Object Id is to be included or used.
ObjectIdGenerators.PropertyGeneratorAbstract place-holder class which is used to denote case where Object Identifier to use comes from a POJO property (getter method or field).
ObjectIdGenerators.StringIdGeneratorImplementation that will accept arbitrary (but unique) String Ids on deserialization, and (by default) use random UUID generation similar to
ObjectIdGenerators.UUIDGeneratorfor generation ids.
ObjectIdGenerators.UUIDGeneratorImplementation that just uses
UUIDs as reliably unique identifiers: downside is that resulting String is 36 characters long.
