org.hibernate.engine.query.spi.sql.NativeSQLQuerySpecification
Defines the specification or blue-print for a native-sql query. Essentially a simple struct containing the information needed to "translate" a native-sql query and cache that translated representation. Also used as the key by which the native-sql query plans are cached. @author Steve Ebersole
