Class ObjectIdGenerators.IntSequenceGenerator

java.lang.Object

com.fasterxml.jackson.annotation.ObjectIdGenerator<T>

com.fasterxml.jackson.annotation.ObjectIdGenerators.IntSequenceGenerator

All Implemented Interfaces:

Serializable

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.

Modifier and Type	Method and Description
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 SerializerProvider (2.x) / SerializationContext (3.x), 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 SerializerProvider (2.x) / SerializationContext (3.x)); 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.
