 com.mysql.jdbc.ResultSetRow
| ResultSetRow | | abstract public class ResultSetRow (Code) | | Classes that implement this interface represent one row of data from the
MySQL server that might be stored in different ways depending on whether the
result set was streaming (so they wrap a reusable packet), or whether the
result set was cached or via a server-side cursor (so they represent a
byte[][]).
Notice that no bounds checking is expected for implementors
of this interface, it happens in ResultSetImpl.
