Uses of ObjectIdGenerator in com.fasterxml.jackson.annotation

Subclasses of ObjectIdGenerator in com.fasterxml.jackson.annotation

Modifier and Type	Class and Description
static class	ObjectIdGenerators.IntSequenceGenerator Simple sequence-number based generator, which uses basic Java ints (starting with value 1) as Object Identifiers.
static class	ObjectIdGenerators.None Abstract 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.
static class	ObjectIdGenerators.PropertyGenerator Abstract place-holder class which is used to denote case where Object Identifier to use comes from a POJO property (getter method or field).
static class	ObjectIdGenerators.UUIDGenerator Implementation that just uses UUIDs as reliably unique identifiers: downside is that resulting String is 36 characters long.

Methods in com.fasterxml.jackson.annotation that return ObjectIdGenerator

Modifier and Type	Method and Description
ObjectIdGenerator<Integer>	ObjectIdGenerators.IntSequenceGenerator.forScope(Class<?> scope)
ObjectIdGenerator<UUID>	ObjectIdGenerators.UUIDGenerator.forScope(Class<?> scope) Can just return base instance since this is essentially scopeless
abstract ObjectIdGenerator<T>	ObjectIdGenerator.forScope(Class<?> scope) Factory method to create a blueprint instance for specified scope.
ObjectIdGenerator<Integer>	ObjectIdGenerators.IntSequenceGenerator.newForSerialization(Object context)
ObjectIdGenerator<UUID>	ObjectIdGenerators.UUIDGenerator.newForSerialization(Object context) Can just return base instance since this is essentially scopeless
abstract ObjectIdGenerator<T>	ObjectIdGenerator.newForSerialization(Object context) Factory method called to create a new instance to use for serialization: needed since generators may have state (next id to produce).

Methods in com.fasterxml.jackson.annotation with parameters of type ObjectIdGenerator

Modifier and Type	Method and Description
boolean	ObjectIdGenerators.UUIDGenerator.canUseFor(ObjectIdGenerator<?> gen) Since UUIDs are always unique, let's fully ignore scope definition
abstract boolean	ObjectIdGenerator.canUseFor(ObjectIdGenerator<?> gen) Method called to check whether this generator instance can be used for Object Ids of specific generator type and scope; determination is based by passing a configured "blueprint" (prototype) instance; from which the actual instances are created (using newForSerialization(java.lang.Object)).
