Examples of org.apache.lenya.workflow.SynchronizedWorkflowInstances

org.apache.lenya.workflow.SynchronizedWorkflowInstances
Synchronized workflow instances.

A set of workflow instances with the same workflow schema can be synchronized. If a transition in this schema is marked as synchronized, it can only be invoked on all instances in the set at the same time.

When a workflow event is invoked on a set of synchronized workflow instances, the transition is invoked only if
- all instances are in the source state of the transition, and
- all conditions of the transition are complied for all instances.
Then the transition is invoked for all instances in the set.

A common usecase of this concept is the simultaneous publishing of a set of documents (all language versions of a document, a section, ...).


          Document document = builder.buildDocument(publication, url);
          WorkflowFactory factory = WorkflowFactory.newInstance();


          if (factory.hasWorkflow(document)) {
            SynchronizedWorkflowInstances instance =
              factory.buildSynchronizedInstance(document);


            authorized = false;


            Situation situation = WorkflowHelper.buildSituation(request);
            Event[] events = instance.getExecutableEvents(situation);
            int i = 0;


            while (!authorized && (i < events.length)) {
              if (events[i].getName().equals(event)) {
                authorized = true;
