Example 1 with ActivitiEventDispatcher

use of org.activiti.engine.delegate.event.ActivitiEventDispatcher in project Activiti by Activiti.

the class DeploymentManager method removeDeployment.

public void removeDeployment(String deploymentId, boolean cascade) {
    DeploymentEntityManager deploymentEntityManager = Context.getCommandContext().getDeploymentEntityManager();

    if (deployment == null)

    ActivitiEventDispatcher eventDispatcher = Context.getProcessEngineConfiguration().getEventDispatcher();

        // Since all process definitions are deleted by a single query, we should dispatch the events in this loop
