public String getElementTableAlias()

Implements org.hibernate.loader.plan.exec.spi.CollectionReferenceAliases.getElementTableAlias.

Doc from org.hibernate.loader.plan.exec.spi.CollectionReferenceAliases.getElementTableAlias.

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.

Returns:String

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

public EntityReferenceAliases getEntityElementAliases()

Implements org.hibernate.loader.plan.exec.spi.CollectionReferenceAliases.getEntityElementAliases.

Doc from org.hibernate.loader.plan.exec.spi.CollectionReferenceAliases.getEntityElementAliases.

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

Returns:EntityReferenceAliases

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