org.hibernate.loader.BasicLoader

org.hibernate.loader.OuterJoinLoader

直接已知子类:

AbstractEntityLoader, CollectionElementLoader, CollectionLoader, CriteriaLoader

public abstract class OuterJoinLoader
extends BasicLoader

Implements logic for walking a tree of associated classes. Generates an SQL select string containing all properties of those classes. Tables are joined using an ANSI-style left outer join.

方法详细资料

getDialect

protected final Dialect getDialect()

getSuffixes

protected String[] getSuffixes()

指定者:

getSuffixes 在类中 BasicLoader

getCollectionSuffixes

protected String[] getCollectionSuffixes()

指定者:

getCollectionSuffixes 在类中 BasicLoader

getSQLString

public final String getSQLString()

从类复制的说明: Loader

The SQL query string to be called; implemented by all subclasses

指定者:

getSQLString 在类中 Loader

返回:

The sql command this loader should use to get its ResultSet.

getEntityPersisters

protected final Loadable[] getEntityPersisters()

从类复制的说明: Loader

An array of persisters of entity classes contained in each row of results; implemented by all subclasses

指定者:

getEntityPersisters 在类中 Loader

返回:

The entity persisters.

getOwners

protected int[] getOwners()

从类复制的说明: Loader

An array of indexes of the entity that owns a one-to-one association to the entity at the given index (-1 if there is no "owner"). The indexes contained here are relative to the result of Loader.getEntityPersisters().

覆盖:

getOwners 在类中 Loader

返回:

The owner indicators (see discussion above).

getOwnerAssociationTypes

protected EntityType[] getOwnerAssociationTypes()

从类复制的说明: Loader

An array of the owner types corresponding to the Loader.getOwners() returns. Indices indicating no owner would be null here.

覆盖:

getOwnerAssociationTypes 在类中 Loader

返回:

The types for the owners.

getLockModes

protected LockMode[] getLockModes(LockOptions lockOptions)

从类复制的说明: Loader

What lock options does this load entities with?

指定者:

getLockModes 在类中 Loader

参数:

lockOptions - a collection of lock options specified dynamically via the Query interface

getLockOptions

protected LockOptions getLockOptions()

getLoadQueryInfluencers

public LoadQueryInfluencers getLoadQueryInfluencers()

getAliases

protected final String[] getAliases()

从类复制的说明: Loader

Get the SQL table aliases of entities whose associations are subselect-loadable, returning null if this loader does not support subselect loading

覆盖:

getAliases 在类中 Loader

getCollectionPersisters

protected final CollectionPersister[] getCollectionPersisters()

从类复制的说明: Loader

An (optional) persister for a collection to be initialized; only collection loaders return a non-null value

覆盖:

getCollectionPersisters 在类中 Loader

getCollectionOwners

protected final int[] getCollectionOwners()

从类复制的说明: Loader

Get the index of the entity that owns the collection, or -1 if there is no owner in the query results (ie. in the case of a collection initializer) or no collection.

覆盖:

getCollectionOwners 在类中 Loader

initFromWalker

protected void initFromWalker(JoinWalker walker)
