详细说明

在处理读取历史事件的请求时，该类的实例用于存储已读取的节点、其事件以及状态码的相关信息。历史读取响应的 finished 信号将返回一个 QOpcUaHistoryEvent 对象列表，该列表可被解析以查看请求的结果。

成员函数文档

QOpcUaHistoryEvent::QOpcUaHistoryEvent()

构建了一个无效的历史事件条目。

`[explicit]` QOpcUaHistoryEvent::QOpcUaHistoryEvent(const QString &nodeId)

创建一个历史事件条目，并记录其对应的节点。

QOpcUaHistoryEvent::QOpcUaHistoryEvent(const QOpcUaHistoryEvent &other)

根据other 构建一个历史事件条目。

`[constexpr noexcept default]` QOpcUaHistoryEvent::QOpcUaHistoryEvent(QOpcUaHistoryEvent &&other)

从other 创建一个新的历史事件对象。

注意： 被移动的源对象 other 将处于部分形成状态，在此状态下，唯一有效的操作是销毁和赋值。

`[noexcept]` QOpcUaHistoryEvent::~QOpcUaHistoryEvent()

删除历史事件项。

void QOpcUaHistoryEvent::addEvent(const QVariantList &value)

添加由 `value` 指定的事件字段列表。

int QOpcUaHistoryEvent::count() const

返回可用事件的数量。

QList<QVariantList> QOpcUaHistoryEvent::events() const

返回包含历史记录读取请求结果的QVariantList 对象列表。

QString QOpcUaHistoryEvent::nodeId() const

返回已存储其事件的节点的 nodeId。

另请参阅 setNodeId()。

void QOpcUaHistoryEvent::setNodeId(const QString &nodeId)

将nodeId 设置为nodeId 。

另请参阅 nodeId()。

void QOpcUaHistoryEvent::setStatusCode(QOpcUa::UaStatusCode statusCode)

将状态码设置为statusCode 。

另请参阅 statusCode()。

QOpcUa::UaStatusCode QOpcUaHistoryEvent::statusCode() const

返回一个状态码，用于指示在获取历史事件时是否发生错误。

另请参阅 setStatusCode()。

`[noexcept]` void QOpcUaHistoryEvent::swap(QOpcUaHistoryEvent &other)

将历史事件对象other 与该历史事件对象进行交换。此操作速度极快，且绝不会失败。

`[noexcept]` QOpcUaHistoryEvent &QOpcUaHistoryEvent::operator=(QOpcUaHistoryEvent &&other)

将other 通过移动赋值操作赋值给此QOpcUaHistoryEvent 实例。

注意： 被移动的对象 other 将处于部分初始化状态，在此状态下，唯一有效的操作是销毁或赋予新值。

QOpcUaHistoryEvent &QOpcUaHistoryEvent::operator=(const QOpcUaHistoryEvent &other)

将other 中的值设置到此历史事件项中。
