 * The mapping in the Java programming language of an SQL {@code REF}
 * value, which is a reference to an SQL structured type value in the database.
 * <P>
 * SQL {@code REF} values are stored in a table that contains
 * instances of a referenceable SQL structured type, and each {@code REF}
 * value is a unique identifier for one instance in that table.
 * An SQL {@code REF} value may be used in place of the
 * SQL structured type it references, either as a column value in a
 * table or an attribute value in a structured type.
 * <P>
 * Because an SQL {@code REF} value is a logical pointer to an
 * SQL structured type, a {@code Ref} object is by default also a logical
 * pointer. Thus, retrieving an SQL {@code REF} value as
 * a {@code Ref} object does not materialize
 * the attributes of the structured type on the client.
 * <P>
 * A {@code Ref} object can be stored in the database using the
 * {@code PreparedStatement.setRef} method.
  * <p>
 * All methods on the {@code Ref} interface must be fully implemented if the
 * JDBC driver supports the data type.
