    TaskQuery taskQuery = taskService.createTaskQuery();
    if (getTasksPayload.getProcessInstanceId() != null) {

the class TaskAdminRuntimeImpl method delete.

@Override

    // we might need to create an empty shell with the task ID and Status only
    Task task = task(deleteTaskPayload.getTaskId());
    TaskImpl deletedTaskData = new TaskImpl(task.getId(), task.getName(), Task.TaskStatus.CANCELLED);

    }
    taskService.deleteTask(deleteTaskPayload.getTaskId(), deleteTaskPayload.getReason(), true);
    return deletedTaskData;
}

Example 3 with Task

use of org.activiti.api.task.model.Task in project Activiti by Activiti.

the class TaskRuntimeImpl method claim.

@Override

    Task task;
    try {
        task = task(claimTaskPayload.getTaskId());

Example 4 with Task

use of org.activiti.api.task.model.Task in project Activiti by Activiti.

the class TaskRuntimeImpl method complete.

@Override
public Task complete(CompleteTaskPayload completeTaskPayload) {
    // @TODO: not the most efficient way to return the just completed task, improve
    // we might need to create an empty shell with the task ID and Status only
    Task task;

    }
    if (!task.getAssignee().equals(authenticatedUserId)) {

    }
    taskRuntimeHelper.handleCompleteTaskPayload(completeTaskPayload);
    taskService.complete(completeTaskPayload.getTaskId(), completeTaskPayload.getVariables(), true);
    ((TaskImpl) task).setStatus(Task.TaskStatus.COMPLETED);
    return task;
