Example 1 with CorrelationManager

use of org.jbpm.process.core.correlation.CorrelationManager in project jbpm by kiegroup.

the class ProcessHandler method postProcessCollaborations.

private void postProcessCollaborations(RuleFlowProcess process, ExtensibleXmlParser parser) {
    // now we wire correlation process subscriptions
    CorrelationManager correlationManager = process.getCorrelationManager();
    for (Message message : HandlerUtil.messages(parser).values()) {
        correlationManager.newMessage(message.getId(), message.getName(), message.getType());
    }
    // only the ones this process is member of
    List<Collaboration> collaborations = HandlerUtil.collaborations(parser).values().stream().filter(c -> c.getProcessesRef().contains(process.getId())).collect(Collectors.toList());
    for (Collaboration collaboration : collaborations) {
        for (CorrelationKey key : collaboration.getCorrelationKeys()) {
            correlationManager.newCorrelation(key.getId(), key.getName());
            List<CorrelationProperty> properties = key.getPropertiesRef().stream().map(k -> HandlerUtil.correlationProperties(parser).get(k)).collect(Collectors.toList());

                    correlationManager.addMessagePropertyExpression(key.getId(), messageRef, correlationProperty.getId(), evaluator);
                });
            }
