Uses of Class com.fasterxml.jackson.annotation.ObjectIdGenerator

Uses of ObjectIdGenerator in com.fasterxml.jackson.annotation

Subclasses of ObjectIdGenerator in com.fasterxml.jackson.annotation
Modifier and Type	Class	Description
`private static class`	`ObjectIdGenerators.Base<T>`	Shared base class for concrete implementations.
`static class`	`ObjectIdGenerators.IntSequenceGenerator`	Simple sequence-number based generator, which uses basic Java `int`s (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.StringIdGenerator`	Implementation that will accept arbitrary (but unique) String Ids on deserialization, and (by default) use random UUID generation similar to `ObjectIdGenerators.UUIDGenerator` for generation ids.
`static class`	`ObjectIdGenerators.UUIDGenerator`	Implementation that just uses `UUID`s 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	Description
`abstract ObjectIdGenerator<T>`	ObjectIdGenerator.`forScope(java.lang.Class<?> scope)`	Factory method to create a blueprint instance for specified scope.
`ObjectIdGenerator<java.lang.Integer>`	ObjectIdGenerators.IntSequenceGenerator.`forScope(java.lang.Class<?> scope)`
`ObjectIdGenerator<java.lang.String>`	ObjectIdGenerators.StringIdGenerator.`forScope(java.lang.Class<?> scope)`
`ObjectIdGenerator<java.util.UUID>`	ObjectIdGenerators.UUIDGenerator.`forScope(java.lang.Class<?> scope)`	Can just return base instance since this is essentially scopeless
`abstract ObjectIdGenerator<T>`	ObjectIdGenerator.`newForSerialization(java.lang.Object context)`	Factory method called to create a new instance to use for serialization: needed since generators may have state (next id to produce).
`ObjectIdGenerator<java.lang.Integer>`	ObjectIdGenerators.IntSequenceGenerator.`newForSerialization(java.lang.Object context)`
`ObjectIdGenerator<java.lang.String>`	ObjectIdGenerators.StringIdGenerator.`newForSerialization(java.lang.Object context)`
`ObjectIdGenerator<java.util.UUID>`	ObjectIdGenerators.UUIDGenerator.`newForSerialization(java.lang.Object context)`	Can just return base instance since this is essentially scopeless

Methods in com.fasterxml.jackson.annotation that return types with arguments of type ObjectIdGenerator
Modifier and Type	Method	Description
`java.lang.Class<? extends ObjectIdGenerator<?>>`	`generator()`	Generator to use for producing Object Identifier for objects: either one of pre-defined generators from `ObjectIdGenerator`, or a custom generator.

Methods in com.fasterxml.jackson.annotation with parameters of type ObjectIdGenerator
Modifier and Type	Method	Description
`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)`).
`boolean`	ObjectIdGenerators.Base.`canUseFor(ObjectIdGenerator<?> gen)`
`boolean`	ObjectIdGenerators.StringIdGenerator.`canUseFor(ObjectIdGenerator<?> gen)`
`boolean`	ObjectIdGenerators.UUIDGenerator.`canUseFor(ObjectIdGenerator<?> gen)`	Since UUIDs are always unique, let's fully ignore scope definition
