Examples with VariableEvent org.camunda.bpm.engine.impl.core.variable.event.VariableEvent used on opensource projects

Example 1 with VariableEvent

use of org.camunda.bpm.engine.impl.core.variable.event.VariableEvent in project camunda-bpm-platform by camunda.

the class ConditionalEventHandler method handleEvent.

@Override
public void handleEvent(EventSubscriptionEntity eventSubscription, Object payload, String businessKey, CommandContext commandContext) {
    VariableEvent variableEvent;
    if (payload == null || payload instanceof VariableEvent) {
        variableEvent = (VariableEvent) payload;
    } else {
        throw new ProcessEngineException("Payload have to be " + VariableEvent.class.getName() + ", to evaluate condition.");
    }
    ActivityImpl activity = eventSubscription.getActivity();
    ActivityBehavior activityBehavior = activity.getActivityBehavior();
    if (activityBehavior instanceof ConditionalEventBehavior) {
        ConditionalEventBehavior conditionalBehavior = (ConditionalEventBehavior) activityBehavior;
        conditionalBehavior.leaveOnSatisfiedCondition(eventSubscription, variableEvent);
    } else {
        throw new ProcessEngineException("Conditional Event has not correct behavior: " + activityBehavior);
    }
}

Example 2 with VariableEvent

use of org.camunda.bpm.engine.impl.core.variable.event.VariableEvent in project camunda-bpm-platform by camunda.

the class CmmnExecution method invokeVariableListeners.
