Class SequenceGenerator

java.lang.Object

org.hibernate.id.SequenceGenerator

All Implemented Interfaces:

ExportableProducer, BulkInsertionCapableIdentifierGenerator, Configurable, IdentifierGenerator, PersistentIdentifierGenerator

Direct Known Subclasses:

SequenceHiLoGenerator, SequenceIdentityGenerator

Deprecated.

Use SequenceStyleGenerator instead

@Deprecated
public class SequenceGenerator
extends Object
implements PersistentIdentifierGenerator, BulkInsertionCapableIdentifierGenerator

sequence

Generates long values using an oracle-style sequence. A higher performance algorithm is SequenceHiLoGenerator.

Mapping parameters supported: sequence, parameters.

Method Summary

Modifier and Type	Method and Description
protected IntegralDataTypeHolder	buildHolder() Deprecated.
void	configure(Type type, Properties params, ServiceRegistry serviceRegistry) Deprecated. Configure this instance, given the value of parameters specified by the user as <param> elements.
String	determineBulkInsertionIdentifierGenerationSelectFragment(SqlStringGenerationContext context) Deprecated. Return the select expression fragment, if any, that generates the identifier values.
Serializable	generate(SharedSessionContractImplementor session, Object obj) Deprecated. Generate a new identifier.
protected IntegralDataTypeHolder	generateHolder(SharedSessionContractImplementor session) Deprecated.
String[]	getAllSqlForTests() Deprecated. Exposed for tests only.
protected Type	getIdentifierType() Deprecated.
QualifiedName	getPhysicalSequenceName() Deprecated.
void	initialize(SqlStringGenerationContext context) Deprecated. Initializes this instance, in particular pre-generates SQL as necessary.
void	registerExportables(Database database) Deprecated. Register database objects used by this identifier generator, e.g.
boolean	supportsBulkInsertionIdentifierGeneration() Deprecated. Given the configuration of this generator, is identifier generation as part of bulk insertion supported? IMPL NOTE : Mainly here to allow stuff like SequenceStyleGenerator which *can* support this based on configuration

getIdentifierType

protected Type getIdentifierType()

Deprecated.

getPhysicalSequenceName

configure

public void configure(Type type,
                      Properties params,
                      ServiceRegistry serviceRegistry)
               throws MappingException

Deprecated.

Description copied from interface: IdentifierGenerator

Configure this instance, given the value of parameters specified by the user as <param> elements.

This method is called just once, following instantiation, and before IdentifierGenerator.registerExportables(Database).

Specified by:

configure in interface Configurable

Specified by:

configure in interface IdentifierGenerator

Parameters:

type - The id property type descriptor

params - param values, keyed by parameter name

serviceRegistry - Access to service that may be needed.

Throws:

MappingException - If configuration fails.

generate

public Serializable generate(SharedSessionContractImplementor session,
                             Object obj)

Deprecated.

Description copied from interface: IdentifierGenerator

Generate a new identifier.

Specified by:

generate in interface IdentifierGenerator

Parameters:

session - The session from which the request originates

obj - the entity or collection (idbag) for which the id is being generated

Returns:

a new identifier

generateHolder

protected IntegralDataTypeHolder generateHolder(SharedSessionContractImplementor session)

Deprecated.

buildHolder

protected IntegralDataTypeHolder buildHolder()

Deprecated.

supportsBulkInsertionIdentifierGeneration

public boolean supportsBulkInsertionIdentifierGeneration()

Deprecated.

Description copied from interface: BulkInsertionCapableIdentifierGenerator

Given the configuration of this generator, is identifier generation as part of bulk insertion supported?

IMPL NOTE : Mainly here to allow stuff like SequenceStyleGenerator which *can* support this based on configuration

Specified by:

supportsBulkInsertionIdentifierGeneration in interface BulkInsertionCapableIdentifierGenerator

Returns:

true if bulk insertions are supported; false otherwise.

determineBulkInsertionIdentifierGenerationSelectFragment

public String determineBulkInsertionIdentifierGenerationSelectFragment(SqlStringGenerationContext context)

Deprecated.

Description copied from interface: BulkInsertionCapableIdentifierGenerator

Return the select expression fragment, if any, that generates the identifier values.

Specified by:

determineBulkInsertionIdentifierGenerationSelectFragment in interface BulkInsertionCapableIdentifierGenerator

Returns:

The identifier value generation fragment (SQL). null indicates that no fragment is needed.

registerExportables

public void registerExportables(Database database)

Deprecated.

Description copied from interface: IdentifierGenerator

Register database objects used by this identifier generator, e.g. sequences, tables, etc.

This method is called just once, after IdentifierGenerator.configure(Type, Properties, ServiceRegistry).

Specified by:

registerExportables in interface ExportableProducer

Specified by:

registerExportables in interface IdentifierGenerator

Parameters:

database - The database instance

initialize

public void initialize(SqlStringGenerationContext context)

Deprecated.

Description copied from interface: IdentifierGenerator

Initializes this instance, in particular pre-generates SQL as necessary.

This method is called after IdentifierGenerator.registerExportables(Database), before first use.

Specified by:

initialize in interface IdentifierGenerator

Parameters:

context - A context to help generate SQL strings
