| columnIds | | int[] columnIds(Code) | | |
| triggerArray | | TriggerDescriptor[] triggerArray(Code) | | This class implements Formatable. That means that it
can write itself to and from a formatted stream. If
you add more fields to this class, make sure that you
also write/read them with the writeExternal()/readExternal()
methods.
If, inbetween releases, you add more fields to this class,
then you should bump the version number emitted by the getTypeFormatId()
method. OR, since this is something that is used
in stored prepared statements, it is ok to change it
if you make sure that stored prepared statements are
invalidated across releases.
