javax.persistence.SqlResultSetMapping
net.sourceforge.jpaxjc.ns.persistence.orm.SqlResultSetMapping
oracle.toplink.essentials.queryframework.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 TopLink Project @see oracle.toplink.essentials.sessions.Project @author Gordon Yorke @since TopLink Java Essentials
org.apache.cayenne.query.SQLResultSetMapping
A metadata object that defines how a DataRow can be converted to result objects. This object provides mapping in a JPA-compliant manner, i.e. the DataRow is mapped either to a single Object or an Object[]. Each object (single result object or an array element object) can be a scalar or a Persistent object. @since 3.0 @author Andrus Adamchik
