org.hibernate.loader.plan.build.internal.returns.BidirectionalEntityReferenceImpl

所有已实现的接口:

BidirectionalEntityReference, EntityReference, FetchSource

public class BidirectionalEntityReferenceImpl
extends Object
implements BidirectionalEntityReference

Represents an entity fetch that is bi-directionally join fetched.

For example, consider an Order entity whose primary key is partially made up of the Customer entity to which it is associated. When we join fetch Customer -> Order(s) and then Order -> Customer we have a bi-directional fetch. This class would be used to represent the Order -> Customer part of that link.

                                        EntityReference targetEntityReference)

方法详细资料

getTargetEntityReference

public EntityReference getTargetEntityReference()

从接口复制的说明: BidirectionalEntityReference

Get the targeted EntityReference

指定者:

getTargetEntityReference 在接口中 BidirectionalEntityReference

返回:

The targeted EntityReference

getPropertyPath

public PropertyPath getPropertyPath()

从接口复制的说明: FetchSource

Get the property path to this fetch source

指定者:

getPropertyPath 在接口中 FetchSource

返回:

The property path

getQuerySpaceUid

public String getQuerySpaceUid()

从接口复制的说明: BidirectionalEntityReference

The query space UID returned using BidirectionalEntityReference.getQuerySpaceUid() must be the same as returned by {@link #getTargetEntityReference()#getQuerySpaceUid()}

指定者:

getQuerySpaceUid 在接口中 BidirectionalEntityReference

指定者:

getQuerySpaceUid 在接口中 EntityReference

指定者:

getQuerySpaceUid 在接口中 FetchSource

返回:

The query space UID.

getFetches

public Fetch[] getFetches()

从接口复制的说明: FetchSource

Retrieve the fetches owned by this fetch source.

指定者:

getFetches 在接口中 FetchSource

返回:

The owned fetches.

getBidirectionalEntityReferences

public BidirectionalEntityReference[] getBidirectionalEntityReferences()

从接口复制的说明: FetchSource

Retrieve the bidirectional entity references owned by this fetch source.

getBidirectionalEntityReferences 在接口中 FetchSource

返回:

The owned bidirectional entity references.

resolveEntityReference

public EntityReference resolveEntityReference()

从接口复制的说明: FetchSource

Resolve the "current" EntityReference, or null if none. If this object is an EntityReference, then this object is returned; otherwise, if this object is a Fetch, then the nearest EntityReference will be resolved from its source, if possible. If no EntityReference can be resolved, null is return.

指定者:

resolveEntityReference 在接口中 FetchSource

返回:

the "current" EntityReference or null if none. .

getEntityPersister

public EntityPersister getEntityPersister()

从接口复制的说明: EntityReference

Retrieves the EntityPersister describing the entity associated with this Return.

指定者:

getEntityPersister 在接口中 EntityReference

返回:

The EntityPersister.

getIdentifierDescription

public EntityIdentifierDescription getIdentifierDescription()

从接口复制的说明: EntityReference

Get the description of this entity's identifier descriptor.

指定者:

getIdentifierDescription 在接口中 EntityReference

返回:

The identifier description.
