public class SingleTableEntityPersister
extends BasicEntityPersister

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.
