Class AsyncPeriodicWork

java.lang.Object

java.util.TimerTask

hudson.triggers.SafeTimerTask

hudson.model.PeriodicWork

hudson.model.AsyncPeriodicWork

All Implemented Interfaces:

ExtensionPoint, Runnable

Direct Known Subclasses:

ConnectionActivityMonitor, DownloadSettings.DailyCheck, FingerprintCleanupThread, Telemetry.TelemetryReporter, WorkspaceCleanupThread

public abstract class AsyncPeriodicWork
extends PeriodicWork

PeriodicWork that takes a long time to run.

Subclasses will implement the execute(TaskListener) method and can carry out a long-running task. This runs in a separate thread so as not to block the timer thread, and this class handles all those details.
