public class HibernateGridDataSource extends Object implements GridDataSource
GridDataSource based on a Hibernate Session and a known
entity class. This implementation does support multiple sort
constraints; however it assumes a direct mapping from sort constraint property to Hibernate property.
This class is not thread-safe; it maintains internal state.
Typically, an instance of this object is created fresh as needed (that is, it is not stored between requests).| Constructor and Description |
