| 31 | This class understands the message protocol and looks up |
| 32 | SQLExceptions based on keys, so that the Local JDBC driver's |
| 33 | messages can be localized. |
| 34 | |
| 35 | REMIND: May want to investigate putting some of this in the protocol |
| 36 | side, for the errors that any Cloudscape JDBC driver might return. |
| 37 | |
| 38 | The ASSERT mechanism is a wrapper of the basic services, |
| 39 | to ensure that failed asserts at this level will behave |
| 40 | well in a JDBC environment. |
