带有参数的 Java 8 流映射

Question

我有这两个函数，我想知道是否可以将参数 deviceEvent.hasAlarm() 传递给 .map(this::sendSMS)

private void processAlarm (DeviceEvent deviceEvent)  {

        notificationsWithGuardians.stream()
                    .filter (notification -> notification.getLevels().contains(deviceEvent.getDeviceMessage().getLevel()))
                    .map(this::sendSMS)
                    .map(this::sendEmail);

    }

    private DeviceAlarmNotification sendSMS (DeviceAlarmNotification notification, DeviceEvent deviceEvent)  {

        if (deviceEvent.hasAlarm()) {       

        }

        return notification;

    }

使用 lambda 代替方法引用。

// ...
.map(n -> sendSMS(n, deviceEvent))
// ...
