public class SerialRef extends Object implements Ref, Serializable, Cloneable
Ref
object, which is the mapping in the Java programming language of an SQL REF
value. The SerialRef
class provides a constructor for creating a SerialRef
instance from a Ref
object and provides methods for getting and setting the Ref
object.
