The SQLIdGenerator
and TransientIdGenerator
implement the atg.service.idgen.IdGenerator
interface, and extend the AbstractSequentialIdGenerator
abstract class. If you want to create your own IdGenerator
implementations, it is probably best to extend AbstractSequentialIdGenerator
.
The SQLIdGenerator
and TransientIdGenerator
implementations happen to generate sequential IDs, but that does not have to be true for all IdGenerator
implementations. The AbstractSequentialIdGenerator
includes two empty hook methods, postGenerateLongId()
and postGenerateStringId()
, that you can override in a subclass to provide additional ID generation logic.
