类 NamedQueryLoader

java.lang.Object

org.hibernate.persister.entity.NamedQueryLoader

所有已实现的接口:

UniqueEntityLoader

public final class NamedQueryLoader
extends Object
implements UniqueEntityLoader

Not really a Loader, just a wrapper around a named query. Used when the metadata has named a query to use for loading an entity (using Loader or <loader/>).

参数:

queryName - The name of the named query to use

persister - The corresponding persister for the entity we are loading

方法详细资料

load

public Object load(Serializable id,
                   Object optionalObject,
                   SharedSessionContractImplementor session,
                   LockOptions lockOptions)

从接口复制的说明: UniqueEntityLoader

Load an entity instance by id. If optionalObject is supplied (non-null, the entity state is loaded into that object instance instead of instantiating a new one.

指定者:

load 在接口中 UniqueEntityLoader

参数:

id - The id to be loaded

optionalObject - The (optional) entity instance in to which to load the state

session - The session from which the request originated

lockOptions - The lock options.

返回:

The loaded entity
