QBluetoothServiceInfo Class

Member Function Documentation

QBluetoothServiceInfo::QBluetoothServiceInfo(const QBluetoothServiceInfo &other)

Construct a new QBluetoothServiceInfo that is a copy of other.

The two copies continue to share the same underlying data which does not detach upon write.

QBluetoothServiceInfo::QBluetoothServiceInfo()

Construct a new invalid QBluetoothServiceInfo;

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

Makes a copy of the other and assigns it to this QBluetoothServiceInfo object. The two copies continue to share the same service and registration details.

QBluetoothServiceInfo::~QBluetoothServiceInfo()

Destroys the QBluetoothServiceInfo object.

QVariant QBluetoothServiceInfo::attribute(quint16 attributeId) const

Returns the value of the attribute attributeId.

See also setAttribute().

QList<quint16> QBluetoothServiceInfo::attributes() const

Returns a list of all attribute ids that the QBluetoothServiceInfo object has.

bool QBluetoothServiceInfo::contains(quint16 attributeId) const

Returns true if the QBluetoothServiceInfo object contains the attribute attributeId, otherwise returns false.

QBluetoothDeviceInfo QBluetoothServiceInfo::device() const

Returns the address of the Bluetooth device that provides this service.

See also setDevice().

bool QBluetoothServiceInfo::isComplete() const

Returns true if the QBluetoothServiceInfo object is considered complete, otherwise returns false.

A complete QBluetoothServiceInfo object contains a ProtocolDescriptorList attribute.

bool QBluetoothServiceInfo::isRegistered() const

Returns true if the service information is registered with the platform's Service Discovery Protocol (SDP) implementation, otherwise returns false.

bool QBluetoothServiceInfo::isValid() const

Returns true if the QBluetoothServiceInfo object is valid, otherwise returns false.

An invalid QBluetoothServiceInfo object will have no attributes.

QBluetoothServiceInfo::Sequence QBluetoothServiceInfo::protocolDescriptor(QBluetoothUuid::ProtocolUuid protocol) const

Returns the protocol parameters as a QBluetoothServiceInfo::Sequence for protocol protocol.

An empty QBluetoothServiceInfo::Sequence is returned if protocol is not supported.

int QBluetoothServiceInfo::protocolServiceMultiplexer() const

This is a convenience function. Returns the protocol/service multiplexer for services which support the L2CAP protocol, otherwise returns -1.

This function is equivalent to extracting the information from QBluetoothServiceInfo::Sequence returned by QBluetoothServiceInfo::attribute(QBluetoothServiceInfo::ProtocolDescriptorList).

bool QBluetoothServiceInfo::registerService(const QBluetoothAddress &localAdapter = QBluetoothAddress())

Registers this service with the platform's Service Discovery Protocol (SDP) implementation, making it findable by other devices when they perform service discovery. Returns true if the service is successfully registered, otherwise returns false. Once registered changes to the record cannot be made. The service must be unregistered and registered again with the changes.

The localAdapter parameter determines the local Bluetooth adapter under which the service should be registered. If localAdapter is null the default Bluetooth adapter will be used. If this service info object is already registered via a local adapter and this is function is called using a different local adapter, the previous registration is removed and the service reregistered using the new adapter.

void QBluetoothServiceInfo::removeAttribute(quint16 attributeId)

Removes the attribute attributeId from the QBluetoothServiceInfo object.

If the service information is already registered with the platforms SDP database, the database entry will not be updated until registerService() was called again.

int QBluetoothServiceInfo::serverChannel() const

This is a convenience function. Returns the server channel for services which support the RFCOMM protocol, otherwise returns -1.

This function is equivalent to extracting the information from QBluetoothServiceInfo::Sequence returned by QBluetoothServiceInfo::attribute(QBluetootherServiceInfo::ProtocolDescriptorList).

quint8 QBluetoothServiceInfo::serviceAvailability() const

This is a convenience function. It is equivalent to calling attribute(QBluetoothServiceInfo::ServiceAvailability).toUInt().

Returns the availability of the service.

See also setServiceAvailability() and attribute().

QList<QBluetoothUuid> QBluetoothServiceInfo::serviceClassUuids() const

Returns a list of UUIDs describing the service classes that this service conforms to.

This is a convenience function. It is equivalent to calling attribute(QBluetoothServiceInfo::ServiceClassIds).value<QBluetoothServiceInfo::Sequence>() and subsequently iterating over its QBluetoothUuid entries.

See also attribute().

QString QBluetoothServiceInfo::serviceDescription() const

This is a convenience function. It is equivalent to calling attribute(QBluetoothServiceInfo::ServiceDescription).toString().

Returns the service description in the primary language.

See also setServiceDescription() and attribute().

QString QBluetoothServiceInfo::serviceName() const

This is a convenience function. It is equivalent to calling attribute(QBluetoothServiceInfo::ServiceName).toString().

Returns the service name in the primary language.

See also setServiceName() and attribute().

QString QBluetoothServiceInfo::serviceProvider() const

This is a convenience function. It is equivalent to calling attribute(QBluetoothServiceInfo::ServiceProvider).toString().

Returns the service provider in the primary language.

See also setServiceProvider() and attribute().

QBluetoothUuid QBluetoothServiceInfo::serviceUuid() const

This is a convenience function. It is equivalent to calling attribute(QBluetoothServiceInfo::ServiceId).value<QBluetoothUuid>().

Returns the custom UUID of the service. This UUID may be null. UUIDs based on Bluetooth SIG standards should be retrieved via serviceClassUuids().

See also setServiceUuid() and attribute().

void QBluetoothServiceInfo::setAttribute(quint16 attributeId, const QVariant &value)

Sets the attribute identified by attributeId to value.

If the service information is already registered with the platform's SDP database, the database entry will not be updated until registerService() was called again.

Note: If an attribute expectes a byte-encoded value (e.g. Bluetooth HID services), it should be set as QByteArray.

See also attribute(), isRegistered(), and registerService().

void QBluetoothServiceInfo::setAttribute(quint16 attributeId, const QBluetoothUuid &value)

This is a convenience function.

Sets the attribute identified by attributeId to value.

If the service information is already registered with the platform's SDP database, the database entry will not be updated until registerService() was called again.

void QBluetoothServiceInfo::setAttribute(quint16 attributeId, const QBluetoothServiceInfo::Sequence &value)

This is a convenience function.

Sets the attribute identified by attributeId to value.

If the service information is already registered with the platform's SDP database, the database entry will not be updated until registerService() was called again.

void QBluetoothServiceInfo::setAttribute(quint16 attributeId, const QBluetoothServiceInfo::Alternative &value)

This is a convenience function.

Sets the attribute identified by attributeId to value.

If the service information is already registered with the platform's SDP database, the database entry will not be updated until registerService() was called again.

void QBluetoothServiceInfo::setDevice(const QBluetoothDeviceInfo &device)

Sets the Bluetooth device that provides this service to device.

See also device().

void QBluetoothServiceInfo::setServiceAvailability(quint8 availability)

This is a convenience function. It is equivalent to calling setAttribute(QBluetoothServiceInfo::ServiceAvailability, availability).

This is a convenience function. It is equivalent to calling setAttribute(QBluetoothServiceInfo::ServiceDescription, description).

Sets the service description in the primary language to description.

See also serviceDescription() and setAttribute().

void QBluetoothServiceInfo::setServiceName(const QString &name)

This is a convenience function. It is equivalent to calling setAttribute(QBluetoothServiceInfo::ServiceName, name).

Sets the service name in the primary language to name.

See also serviceName() and setAttribute().

void QBluetoothServiceInfo::setServiceProvider(const QString &provider)

This is a convenience function. It is equivalent to calling setAttribute(QBluetoothServiceInfo::ServiceProvider, provider).

Sets the service provider in the primary language to provider.

See also serviceProvider() and setAttribute().

void QBluetoothServiceInfo::setServiceUuid(const QBluetoothUuid &uuid)

This is a convenience function. It is equivalent to calling setAttribute(QBluetoothServiceInfo::ServiceId, uuid).

Sets the custom service UUID to uuid. This function should not be used to set a standardized service UUID.

See also serviceUuid() and setAttribute().

QBluetoothServiceInfo::Protocol QBluetoothServiceInfo::socketProtocol() const

Returns the protocol that the QBluetoothServiceInfo object uses.

bool QBluetoothServiceInfo::unregisterService()

Unregisters this service with the platform's Service Discovery Protocol (SDP) implementation. After this, the service will no longer be findable by other devices through service discovery.

Returns true if the service is successfully unregistered, otherwise returns false.
