类 SequenceGenerator

java.lang.Object

org.hibernate.id.SequenceGenerator

所有已实现的接口:

ExportableProducer, BulkInsertionCapableIdentifierGenerator, Configurable, IdentifierGenerator, PersistentIdentifierGenerator

直接已知子类:

SequenceHiLoGenerator, SequenceIdentityGenerator

@Deprecated
public class SequenceGenerator
extends Object
implements PersistentIdentifierGenerator, BulkInsertionCapableIdentifierGenerator, Configurable

已过时。

Use SequenceStyleGenerator instead

sequence

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

Mapping parameters supported: sequence, parameters.

PARAMETERS

@Deprecated
public static final String PARAMETERS

已过时。

No longer supported. To specify initial-value or increment use the org.hibernate.id.enhanced.SequenceStyleGenerator generator instead.

The parameters parameter, appended to the create sequence DDL. For example (Oracle): INCREMENT BY 1 START WITH 1 MAXVALUE 100 NOCACHE.

getIdentifierType

protected Type getIdentifierType()

已过时。

generatorKey

public Object generatorKey()

已过时。

从接口复制的说明: PersistentIdentifierGenerator

Return a key unique to the underlying database objects. Prevents us from trying to create/remove them multiple times.

指定者:

generatorKey 在接口中 PersistentIdentifierGenerator

返回:

Object an identifying key for this generator

getSequenceName

public String getSequenceName()

已过时。

configure

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

已过时。

从接口复制的说明: Configurable

Configure this instance, given the value of parameters specified by the user as <param> elements. This method is called just once, following instantiation.

指定者:

configure 在接口中 Configurable

参数:

type - The id property type descriptor

params - param values, keyed by parameter name

serviceRegistry - Access to service that may be needed.

抛出:

MappingException

generate

public Serializable generate(SharedSessionContractImplementor session,
                             Object obj)

已过时。

从接口复制的说明: IdentifierGenerator

Generate a new identifier.

指定者:

generate 在接口中 IdentifierGenerator

参数:

session - The session from which the request originates

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

返回:

a new identifier

generateHolder

protected IntegralDataTypeHolder generateHolder(SharedSessionContractImplementor session)

已过时。

buildHolder

protected IntegralDataTypeHolder buildHolder()

已过时。

sqlCreateStrings

public String[] sqlCreateStrings(Dialect dialect)
                          throws HibernateException

已过时。

从接口复制的说明: PersistentIdentifierGenerator

The SQL required to create the underlying database objects.

指定者:

sqlCreateStrings 在接口中 PersistentIdentifierGenerator

参数:

dialect - The dialect against which to generate the create command(s)

返回:

The create command(s)

抛出:

HibernateException - problem creating the create command(s)

sqlDropStrings

public String[] sqlDropStrings(Dialect dialect)
                        throws HibernateException

已过时。

从接口复制的说明: PersistentIdentifierGenerator

The SQL required to remove the underlying database objects.

指定者:

sqlDropStrings 在接口中 PersistentIdentifierGenerator

参数:

dialect - The dialect against which to generate the drop command(s)

返回:

The drop command(s)

抛出:

HibernateException - problem creating the drop command(s)

supportsBulkInsertionIdentifierGeneration

public boolean supportsBulkInsertionIdentifierGeneration()

已过时。

从接口复制的说明: 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

指定者:

supportsBulkInsertionIdentifierGeneration 在接口中 BulkInsertionCapableIdentifierGenerator

返回:

true if bulk insertions are supported; false otherwise.

determineBulkInsertionIdentifierGenerationSelectFragment

public String determineBulkInsertionIdentifierGenerationSelectFragment(Dialect dialect)
