Enum ShutdownJobInterruption

Namespace

Quartz

Assembly

Quartz.dll

When a shutting-down scheduler signals cancellation to the jobs still executing.

public enum ShutdownJobInterruption

Fields

Always = 3

Running jobs are interrupted on every shutdown, whether it waits for them or not.

Never = 0

Running jobs are never interrupted. The default.

WhenNotWaitingForJobs = 1

Running jobs are interrupted only on a shutdown that does not wait for them.

The shutdown is not going to wait, so the alternative is leaving the jobs running with nothing left to report to.

WhenWaitingForJobs = 2

Running jobs are interrupted only on a shutdown that waits for them to finish.

The wait still happens: the jobs are asked to stop and then given as long as they need to, which is how a job that checks its cancellation token gets to unwind cleanly.

Remarks

A shutdown either waits for running jobs to finish or it does not, and interrupting them is a reasonable thing to want in either case — or in only one of them. This says which, in one setting.

Only a job whose execution context implements IInterruptableJobExecutionContext is signalled; a job that ignores its cancellation token runs to completion whatever this says.
