org.eclipse.stardust.engine.core.spi.monitoring

Interface IWorklistMonitor

public interface IWorklistMonitor

An implementor of this interface can provide a worklist monitor which will be informed about changes to the worklist.

Be aware that the notifications are not TX save: You will be informed even if later in TX a rollback will happen and the change is not commited to DB.
To publish an implementor to the engine a file named by the interface's factory has to be created in the '/META-INF/services' folder of the jar.
In this case: org.eclipse.stardust.engine.core.spi.monitoring.IWorklistMonitor
This file needs to contain the qualified class name of the implementor of this interface.

This pattern follows the concept of the JDK6 ServiceLoader.
