[AX 2012] X++ Batch Job Classes?

Hey,

I appreciate the help in my other '[AX 2012]' thread.

OK so I understand that "Batch Jobs" extend "RunBaseBatch" but how do I know what class to use? In the examples I've found on google, people tend to use examples with custom classes like "TestClassXYZ," which doesn't really help me since I don't want to create a batch job in x++ (or at all for that matter).

Is every batch job its own class? Are the names of these classes at all deterministic (like, BatchJob<BatchJobId> or "BatchJob305932145")? What class(es) is(/are) the batch jobs I see in Inqueries > Batch jobs > "Batch Jobs" / "Batch Job History" ?

I don't want to extend RunBaseBatch to make my own -custom- batch job, I just want to run existing batch jobs.

Thanks.
