成员函数文档
[constexpr noexcept] QBluetoothAddress::QBluetoothAddress()
构造一个空蓝牙地址。
[explicit] QBluetoothAddress::QBluetoothAddress(const QString &address)
构建一个新的蓝牙地址并为其分配address 。
address 的格式可以是 XX:XX:XX:XX:XX:XX 或 XXXXXXXXXX，其中 X 是十六进制数字。大小写并不重要。
[explicit constexpr noexcept] QBluetoothAddress::QBluetoothAddress(quint64 address)
构建新的蓝牙地址，并为其分配address 。
[noexcept] void QBluetoothAddress::clear()
将蓝牙地址设置为 00:00:00:00:00:00:00。
[noexcept] bool QBluetoothAddress::isNull() const
如果蓝牙地址为空，则返回 true，否则返回 false。
QString QBluetoothAddress::toString() const
以 XX:XX:XX:XX:XX:XX 的字符串形式返回蓝牙地址。
[noexcept] quint64 QBluetoothAddress::toUInt64() const
以 quint64 返回该蓝牙地址。
相关非成员
[noexcept, since 6.6] size_t qHash(const QBluetoothAddress &key, size_t seed = 0)
返回key 的哈希值，使用seed 作为计算的种子。
此函数在 Qt 6.6 中引入。
bool operator!=(const QBluetoothAddress &a, const QBluetoothAddress &b)
如果两个蓝牙地址a 和b 不相等，则返回true ，否则返回false 。
bool operator<(const QBluetoothAddress &a, const QBluetoothAddress &b)
如果蓝牙地址a 小于b ，则返回 true，否则返回 false。
bool operator==(const QBluetoothAddress &a, const QBluetoothAddress &b)
如果两个蓝牙地址a 和b 相等，则返回true ，否则返回false 。
