AnEntityPersister
implementing theInheritanceType.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.

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 containsSub1
or any of its subtypes, this means thatSub2
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 forentityNameUses
- The entity names under which a table group was used.
-
