org.eclipse.persistence.queries.SQLResultSetMapping

Purpose: Concrete class to represent the SQLResultSetMapping structure as defined by the EJB 3.0 Persistence specification. This class is used by the ResultSetMappingQuery and is a component of the EclipsepLink Project @see org.eclipse.persistence.sessions.Project @author Gordon Yorke @since TopLink Java Essentials
