@Internal
public class UnionSubclassEntityPersister
extends AbstractEntityPersister

An EntityPersister implementing the InheritanceType.TABLE_PER_CLASS mapping strategy for an entity and its inheritance hierarchy.

This is implemented as a separate table for each concrete class, with all inherited attributes persisted as columns of that table.

Specified by:

getSubclassPropertyTableNumber in interface Queryable

Overrides:

getSubclassPropertyTableNumber in class AbstractEntityPersister

Parameters:

propertyName - The name of the property.

Returns:

The number of the table to which the property is mapped.

physicalTableNameForMutation

public String physicalTableNameForMutation(SelectableMapping selectableMapping)

Description copied from class: AbstractEntityPersister

Unfortunately we cannot directly use `SelectableMapping#getContainingTableExpression()` as that blows up for attributes declared on super-type for union-subclass mappings

pruneForSubclasses

public void pruneForSubclasses(TableGroup tableGroup,
                               Map<String,EntityNameUse> entityNameUses)

Description copied from interface: EntityMappingType

Adapts the table group and its table reference as well as table reference joins in a way such that unnecessary tables or joins are omitted if possible, based on the given treated entity names.

The goal is to e.g. remove join inheritance "branches" or union selects that are impossible.

Consider the following example: class BaseEntity {} class Sub1 extends BaseEntity {} class Sub1Sub1 extends Sub1 {} class Sub1Sub2 extends Sub1 {} class Sub2 extends BaseEntity {} class Sub2Sub1 extends Sub2 {} class Sub2Sub2 extends Sub2 {}

If the treatedEntityNames only contains Sub1 or any of its subtypes, this means that Sub2 and all subtypes are impossible, thus the joins/selects for these types shall be omitted in the given table group.

Parameters:

tableGroup - The table group to prune subclass tables for

entityNameUses - The entity names under which a table group was used.

visitConstraintOrderedTables

public void visitConstraintOrderedTables(EntityMappingType.ConstraintOrderedTableConsumer consumer)

visitMutabilityOrderedTables

protected void visitMutabilityOrderedTables(org.hibernate.persister.entity.AbstractEntityPersister.MutabilityOrderedTableConsumer consumer)

Description copied from interface: Queryable
