## Member Function Documentation

### `[constexpr noexcept]` QBluetoothAddress::QBluetoothAddress()

Constructs a null Bluetooth Address.

### `[explicit]` QBluetoothAddress::QBluetoothAddress(const QString &address)

Constructs a new Bluetooth address and assigns address to it.

The format of address can be either XX:XX:XX:XX:XX:XX or XXXXXXXXXXXX, where X is a hexadecimal digit. Case is not important.

### `[explicit constexpr noexcept]` QBluetoothAddress::QBluetoothAddress(quint64 address)

Constructs a new Bluetooth address and assigns address to it.

### `[noexcept]` void QBluetoothAddress::clear()

Sets the Bluetooth address to 00:00:00:00:00:00.

### `[noexcept]` bool QBluetoothAddress::isNull() const

Returns true if the Bluetooth address is null, otherwise returns false.

### QString QBluetoothAddress::toString() const

Returns the Bluetooth address as a string of the form, XX:XX:XX:XX:XX:XX.

### `[noexcept]` quint64 QBluetoothAddress::toUInt64() const

Returns this Bluetooth address as a quint64.

## Related Non-Members

### `[noexcept, since 6.6]` size_t qHash(const QBluetoothAddress &key, size_t seed = 0)

Returns the hash value for the key, using seed to seed the calculation.

This function was introduced in Qt 6.6.

### bool operator!=(const QBluetoothAddress &a, const QBluetoothAddress &b)

Returns `true` if the two Bluetooth addresses a and b are not equal, otherwise returns `false`.

### bool operator<(const QBluetoothAddress &a, const QBluetoothAddress &b)

Returns true if the Bluetooth address a is less than b, otherwise returns false.

### bool operator==(const QBluetoothAddress &a, const QBluetoothAddress &b)

Returns `true` if the two Bluetooth addresses a and b are equal, otherwise returns `false`.
