Overview

Module

• package: org.eclipse.dirigible.sdk.job
• source: job/Scheduled.java

@Scheduled registers a client Java class as a Quartz-managed scheduled job. The annotated class must expose a public no-arg run() method; Dirigible instantiates the class once and invokes run() on the configured cron schedule.

Hot-reload replaces the instance transparently — the old schedule is cancelled and a new one is registered with the updated class.

Example Usage:

import org.eclipse.dirigible.sdk.job.Scheduled;
import org.eclipse.dirigible.sdk.log.Logger;
import org.eclipse.dirigible.sdk.log.Logging;

@Scheduled(expression = "0/30 * * * * ?")
public class CleanupJob {

    private static final Logger LOG = Logging.getLogger("com.acme.cleanup");

    public void run() {
        LOG.info("cleanup tick");
    }
}

@Scheduled

Registers the class as a Quartz job with the given cron expression.

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
public @interface Scheduled { ... }

Attributes

Attribute	Type	Description
expression	String	Quartz cron expression (six or seven fields). For example "0/30 * * * * ?" fires every 30 seconds.

Notes

• The annotated class must expose a public no-arg run() method.
• Hot-reload reinstalls the schedule when the class changes.
• For programmatic / non-cron scheduling, drop a .job JSON descriptor under the project — the Job synchronizer picks it up.
