org.hibernate.loader.Loader
org.hibernate.loader.BasicLoader
Direct Known Subclasses:
CriteriaLoader, OuterJoinLoader, AbstractEntityLoader, OneToManyLoader, CascadeEntityLoader, CollectionElementLoader, EntityLoader, SubselectOneToManyLoader, CollectionLoader, BasicCollectionLoader, QueryLoader, SubselectCollectionLoader, QueryTranslatorImpl, AbstractEntityLoader
Uses the default mapping from property to result set column
alias defined by the entities' persisters. Used when Hibernate
is generating result set column aliases.

 public static String[] generateSuffixes(int length) {

}
Utility method that generates 0_, 1_ suffixes. Subclasses don't
necessarily need to use this algorithm, but it is intended that
they will in most cases. |
