QBluetoothServiceInfo provides information about a service offered by a Bluetooth device. In addition it can be used to register new services on the local device. Note that such a registration only affects the Bluetooth SDP entries. Any server listening for incoming connections (e.g an RFCOMM server) must be started before registerService () is called. Deregistration must happen in the reverse order.
QBluetoothServiceInfo is not a value type in the traditional sense. All copies of the same service info object share the same data as they do not detach upon changing them. This ensures that two copies can (de)register the same Bluetooth service.
On iOS, this class cannot be used because the platform does not expose an API which may permit access to QBluetoothServiceInfo related features.

QBluetoothServiceInfo::
~QBluetoothServiceInfo
()
销毁 QBluetoothServiceInfo 对象。
Returns the value of the attribute attributeId .
另请参阅 setAttribute ().
Returns a list of all attribute ids that the QBluetoothServiceInfo object has.
返回 true 若 QBluetoothServiceInfo object contains the attribute attributeId ，否则返回 false。
Returns the address of the Bluetooth device that provides this service.
另请参阅 setDevice ().
返回 true 若 QBluetoothServiceInfo object is considered complete, otherwise returns false.
A complete QBluetoothServiceInfo object contains a ProtocolDescriptorList 属性。
Returns true if the service information is registered with the platform's Service Discovery Protocol (SDP) implementation, otherwise returns false.
返回 true 若 QBluetoothServiceInfo object is valid, otherwise returns false.
An invalid QBluetoothServiceInfo object will have no attributes.
Returns the protocol parameters as a QBluetoothServiceInfo::Sequence for protocol protocol .
空 QBluetoothServiceInfo::Sequence is returned if protocol 不支持。
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 返回通过 QBluetoothServiceInfo::attribute ( QBluetoothServiceInfo::ProtocolDescriptorList ).
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.
