java.lang.Object net.sf.basedb.clients.jobagent.executors.ThreadJobExecutor
public class ThreadJobExecutor
This is a job executor which executes jobs in the current thread.
This has the disadvantage that a misbehaving job can
interfere with other jobs and the job agent. For example, a
call to System.exit(int)
would result in
all other jobs as well as the job agent getting killed.
The advantage is that there is no overhead in time or memory.
