Class HibernateAdapter

  net.mlw.vlh.adapter.AbstractValueListAdapter
      net.mlw.vlh.adapter.hibernate3.HibernateAdapter

All Implemented Interfaces:

ValueListAdapter

public class HibernateAdapter

extends AbstractValueListAdapter

This adapter wraps the functionality of Hibernate. Add extra functionality such as paging, focusing and validating of current result set. "Hibernate is a powerful, ultra-high performance object/relational persistence and query service for Java. Hibernate lets you develop persistent classes following common Java idiom - including association, inheritance, polymorphism, composition and the Java collections framework. The Hibernate Query Language, designed as a "minimal" object-oriented extension to SQL, provides an elegant bridge between the object and relational worlds. Hibernate also allows you to express queries using native SQL or Java-based Criteria and Example queries. Hibernate is now the most popular object/relational mapping solution for Java." -http://www.hibernate.org/
