Examples of org.jbpm.taskmgmt.def.TaskController

org.jbpm.taskmgmt.def.TaskController
is a controller for one task. this object either delegates to a custom {@link org.jbpm.taskmgmt.def.TaskControllerHandler} or it is configuredwith {@link org.jbpm.context.def.VariableAccess}s to perform the default behaviour of the controller functionality for a task.

    this.priority = task.getPriority();
    this.isSignalling = task.isSignalling();
  }


  void submitVariables() {
    TaskController taskController = (task != null ? task.getTaskController() : null);
    // if there is a task controller,
    if (taskController != null) {
      // the task controller is responsible for copying variables back into the process
      taskController.submitParameters(this);


      // if there is no task controller
    }
    else if ((token != null) && (token.getProcessInstance() != null)) {
      // the default behaviour is that all task-local variables are flushed to the process
