类 IncrementGenerator

java.lang.Object

org.hibernate.id.IncrementGenerator

所有已实现的接口:

Configurable, IdentifierGenerator

public class IncrementGenerator
extends Object
implements IdentifierGenerator, Configurable

increment

An IdentifierGenerator that returns a long, constructed by counting from the maximum primary key value at startup. Not safe for use in a cluster!

Mapping parameters supported, but not usually needed: tables, column. (The tables parameter specified a comma-separated list of table names.)

public IncrementGenerator()

方法详细资料

generate

public Serializable generate(SharedSessionContractImplementor session,
                             Object object)
                      throws HibernateException

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

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

返回:

a new identifier

抛出:

HibernateException - Indicates trouble generating the identifier

configure

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

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
