Class SedaService

java.lang.Object
  org.mule.service.AbstractService
      org.mule.model.seda.SedaService

All Implemented Interfaces:

Serializable, Runnable, EventListener, javax.resource.spi.work.Work, javax.resource.spi.work.WorkListener, MuleContextAware, Disposable, Initialisable, Lifecycle, Startable, Stoppable, NamedObject, Service

public class SedaService
extends AbstractService
implements javax.resource.spi.work.Work, javax.resource.spi.work.WorkListener

A Seda service runs inside a Seda Model and is responsible for managing a Seda Queue and thread pool for a Mule sevice service. In Seda terms this is equivilent to a stage.

Overrides:

doForceStop in class AbstractService

Throws:

MuleException

doStop

protected void doStop()
               throws MuleException

Overrides:

doStop in class AbstractService

Throws:
