方法详细资料

getCollectionTableAlias

public String getCollectionTableAlias()

从接口复制的说明: CollectionReferenceAliases

Obtain the table alias used for the collection table of the CollectionReference.

指定者:

getCollectionTableAlias 在接口中 CollectionReferenceAliases

返回:

The collection table alias.

getElementTableAlias

public String getElementTableAlias()

从接口复制的说明: CollectionReferenceAliases

Obtain the alias of the table that contains the collection element values.

Unlike in the legacy Loader case, CollectionReferences in the LoadPlan code refer to both the collection and the elements *always*. In Loader the elements were handled by EntityPersister associations entries for one-to-many and many-to-many. In LoadPlan we need to describe the collection table/columns as well as the entity element table/columns. For "basic collections" and one-to-many collections, the "element table" and the "collection table" are actually the same. For the many-to-many case this will be different and we need to track it separately.

指定者:

getElementTableAlias 在接口中 CollectionReferenceAliases

返回:

The element table alias. Only different from CollectionReferenceAliases.getCollectionTableAlias() in the case of many-to-many.

getCollectionColumnAliases

public CollectionAliases getCollectionColumnAliases()

从接口复制的说明: CollectionReferenceAliases

Obtain the aliases for the columns related to the collection structure such as the FK, index/key, or identifier (idbag).

指定者:

getCollectionColumnAliases 在接口中 CollectionReferenceAliases

返回:

The collection column aliases.

getEntityElementAliases

public EntityReferenceAliases getEntityElementAliases()

从接口复制的说明: CollectionReferenceAliases

Obtain the entity reference aliases for the element values when the element of the collection is an entity.

指定者:

getEntityElementAliases 在接口中 CollectionReferenceAliases

返回:

The entity reference aliases for the entity element; null if the collection element is not an entity.
