Since: Qt 5.7

qmake: QT += bluetooth

Group: QLowEnergyDescriptorData is part of shared
Detailed Description▲
An object of this class provides a descriptor to be added to a QLowEnergyCharacteristicData object via QLowEnergyCharacteristicData::addDescriptor().
The member functions related to access permissions are only applicable to those types of descriptors for which the Bluetooth specification does not prescribe if and how their values can be accessed.

Member Function Documentation▲
QLowEnergyDescriptorData::QLowEnergyDescriptorData()▲
Creates a new invalid object of this class.
QLowEnergyDescriptorData::QLowEnergyDescriptorData(const QBluetoothUuid &uuid, const QByteArray &value)▲
Creates a new object of this class with UUID and value being provided by uuid and value, respectively.
QLowEnergyDescriptorData::QLowEnergyDescriptorData(const QLowEnergyDescriptorData &other)▲
Constructs a new object of this class that is a copy of other.
QLowEnergyDescriptorData::~QLowEnergyDescriptorData()▲
Destroys this object.
bool QLowEnergyDescriptorData::isReadable() const▲
Returns true if the value of this descriptor is readable and false otherwise.
bool QLowEnergyDescriptorData::isValid() const▲
Returns true if and only if this object has a non-null UUID.
bool QLowEnergyDescriptorData::isWritable() const▲
Returns true if the value of this descriptor is writable and false otherwise.
QBluetooth::AttAccessConstraints QLowEnergyDescriptorData::readConstraints() const▲
Returns the constraints under which the value of this descriptor can be read. This value is only relevant if isReadable() returns true.
void QLowEnergyDescriptorData::setReadPermissions(bool readable, QBluetooth::AttAccessConstraints constraints = QBluetooth::AttAccessConstraints())▲
Specifies whether the value of this descriptor is readable and if so, under which constraints.

void QLowEnergyDescriptorData::setUuid(const QBluetoothUuid &uuid)▲
void QLowEnergyDescriptorData::setValue(const QByteArray &value)▲
Sets the value of this descriptor to value. It will be sent to a peer device exactly the way it is provided here, so callers need to take care of things such as endianness.

void QLowEnergyDescriptorData::setWritePermissions(bool writable, QBluetooth::AttAccessConstraints constraints = QBluetooth::AttAccessConstraints())▲
Specifies whether the value of this descriptor is writable and if so, under which constraints.

void QLowEnergyDescriptorData::swap(QLowEnergyDescriptorData &other)▲
Swaps this object with other.
QBluetoothUuid QLowEnergyDescriptorData::uuid() const▲
QByteArray QLowEnergyDescriptorData::value() const▲
QBluetooth::AttAccessConstraints QLowEnergyDescriptorData::writeConstraints() const▲
Returns the constraints under which the value of this descriptor can be written. This value is only relevant if isWritable() returns true.
QLowEnergyDescriptorData &QLowEnergyDescriptorData::operator=(const QLowEnergyDescriptorData &other)▲
Makes this object a copy of other and returns the new value of this object.
Related Non-Members▲
bool operator!=(const QLowEnergyDescriptorData &a, const QLowEnergyDescriptorData &b)▲
Returns true if a and b are unequal with respect to their public state, otherwise returns false.
bool operator==(const QLowEnergyDescriptorData &a, const QLowEnergyDescriptorData &b)▲
Returns true if a and b are equal with respect to their public state, otherwise returns false.
