      com.fasterxml.jackson.annotation.ObjectIdGenerators.IntSequenceGenerator

Enclosing class:

ObjectIdGenerators

public static final class ObjectIdGenerators.IntSequenceGenerator
extends ObjectIdGenerator<T>

Simple sequence-number based generator, which uses basic Java ints (starting with value 1) as Object Identifiers.

Method Summary

ObjectIdGenerator<Integer>	forScope(Class<?> scope) Factory method to create a blueprint instance for specified scope.
Integer	generateId(Object forPojo) Method used for generating a new Object Identifier to serialize for given POJO.
protected int	initialValue()
ObjectIdGenerator.IdKey	key(Object key) Method for constructing key to use for ObjectId-to-POJO maps.
ObjectIdGenerator<Integer>	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).

Method Detail

initialValue

protected int initialValue()

forScope

public ObjectIdGenerator<Integer> forScope(Class<?> scope)

Description copied from class: ObjectIdGenerator

Factory method to create a blueprint instance for specified scope. Generators that do not use scope may return 'this'.

Specified by:

forScope in class ObjectIdGenerator<Integer>

newForSerialization

public ObjectIdGenerator<Integer> newForSerialization(Object context)

Description copied from class: ObjectIdGenerator

Factory method called to create a new instance to use for serialization: needed since generators may have state (next id to produce).

Note that actual type of 'context' is com.fasterxml.jackson.databind.SerializerProvider, but can not be declared here as type itself (as well as call to this object) comes from databind package.

Specified by:

newForSerialization in class ObjectIdGenerator<Integer>

Parameters:

context - Serialization context object used (of type com.fasterxml.jackson.databind.SerializerProvider; may be needed by more complex generators to access contextual information such as configuration.

key

public ObjectIdGenerator.IdKey key(Object key)

Description copied from class: ObjectIdGenerator

Method for constructing key to use for ObjectId-to-POJO maps.

Specified by:

key in class ObjectIdGenerator<Integer>

generateId

public Integer generateId(Object forPojo)

Description copied from class: ObjectIdGenerator

Method used for generating a new Object Identifier to serialize for given POJO.

Parameters:

forPojo - POJO for which identifier is needed

Returns:

Object Identifier to use.
