org.hibernate.persister.entity.SingleTableEntityPersister
public class SingleTableEntityPersister
The default implementation of the EntityPersister interface. Implements the "table-per-class-hierarchy" or "roll-up" mapping strategy for an entity class and its inheritence hierarchy. This is implemented as a single table holding all classes in the hierarchy with a discrimator column used to determine which concrete class is referenced.

The first dimension here corresponds to the table indexes returned in
Queryable.getConstraintOrderedTableNameClosure().
The second dimension should have the same length across all the elements in
the first dimension. If not, that'd be a problem ;)
