Detailed Description

An object of this class provides a descriptor to be added to a QLowEnergyCharacteristicData object via QLowEnergyCharacteristicData::addDescriptor().

See also QLowEnergyCharacteristicData, QLowEnergyServiceData, and QLowEnergyController::addService.

Member Function Documentation

QLowEnergyDescriptorData::QLowEnergyDescriptorData(const QLowEnergyDescriptorData &other)

Constructs a new object of this class that is a copy of other.

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()

Creates a new invalid object of this class.

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

Makes this object a copy of other and returns the new value of this object.

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.

See also setWritePermissions().

void QLowEnergyDescriptorData::setUuid(const QBluetoothUuid &uuid)

Sets the UUID of this descriptor to uuid.

See also 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.

See also value().

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.

See also setReadPermissions().

void QLowEnergyDescriptorData::swap(QLowEnergyDescriptorData &other)

Swaps this object with other.

QBluetoothUuid QLowEnergyDescriptorData::uuid() const

Returns the UUID of this descriptor.

See also setUuid().

QByteArray QLowEnergyDescriptorData::value() const

Returns the value of this descriptor.

See also setValue().

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.
