Detailed Description

A wrapper around DBus connection object.

Constructor & Destructor Documentation

~DBusConnection()

alexaClientSDK::bluetoothImplementations::blueZ::DBusConnection::~DBusConnection

(

)

Destructor.

Member Function Documentation

close()

void alexaClientSDK::bluetoothImplementations::blueZ::DBusConnection::close

(

)

Closes the connection. All the subscriptions are closed automatically.

create()

static std::unique_ptr<DBusConnection> alexaClientSDK::bluetoothImplementations::blueZ::DBusConnection::create ( GBusType  connectionType = G_BUS_TYPE_SYSTEM )

static

Connects to DBus and returns a new instance of DBusConnection.

Parameters

connectionType

A GBusType of the connection.

Returns

A pointer to DBusConnection instance or nullptr in case of error.

getGDBusConnection()

GDBusConnection* alexaClientSDK::bluetoothImplementations::blueZ::DBusConnection::getGDBusConnection

(

)

Get GDBusConnection pointer

Returns

A pointer to GDBusConnection.

subscribeToSignal()

unsigned int alexaClientSDK::bluetoothImplementations::blueZ::DBusConnection::subscribeToSignal	(	const char *	serviceName,
		const char *	interfaceName,
		const char *	member,
		const char *	firstArgumentFilter,
		GDBusSignalCallback	callback,
		gpointer	userData
	)

Subscribes a callback to DBus signal

Parameters

serviceName	DBus service name. E.g.: "org.bluez"
interfaceName	Name of the DBus interface to listen to. E.g.: "org.freedesktop.DBus.ObjectManager"
member	Name of the interface member (event name). E.g.: "InterfacesAdded"
firstArgumentFilter	A string to filter the first argument of the event callback with. Null if no filter applied. For BlueZ the first argument could contain the ObjectPath of the object that is being added/removed or changed.
callback	Callback to be called by DBus
userData	A pointer to be passed to a callback

Returns

id of the callback created or 0 on error.

Remarks

DBusConnection internally keeps list of all subscriptions made. They all will be closed in the destructor. For most of the cases we don't need the unsubscribing in runtime, so this is left undone now.
