Checks whether the conversion job has finished.
true if the conversion has finished; otherwise, false. The default value is false.
The value of IsCompleted will be set to true when the runner has completed the conversion. The value is updated when StatusJobDataRunner.QueryJobStatus is called.
Use JobStatus to query the status of job and whether it has completed successfully or was aborted because of errors.
For an example, refer to StatusJobDataRunner.
