Detailed Description

The OptionalInterfaceFactory class is a helper class for high-level D-Bus proxy classes willing to offer access to shared instances of interface proxies for optional interfaces.

To use this helper in a subclass of DBusProxy (say, ExampleObject), ExampleObject should inherit from OptionalInterfaceFactory<ExampleObject>, and call OptionalInterfaceFactory(this) in its constructor's initialization list.

Template Parameters:
DBusProxySubclassA subclass of DBusProxy

Member Enumeration Documentation

Specifies if the interface being supported by the remote object should be checked by optionalInterface() and the convenience functions for it.

See also:
optionalInterface()
Enumerator:
CheckInterfaceSupported 

Don't return an interface instance unless it can be guaranteed that the remote object actually implements the interface.

BypassInterfaceCheck 

Return an interface instance even if it can't be verified that the remote object supports the interface.


Constructor & Destructor Documentation

Tp::OptionalInterfaceFactory::OptionalInterfaceFactory ( DBusProxySubclass *  this_) [inline]

Class constructor.

Parameters:
this_The class to which this OptionalInterfaceFactory is attached
Tp::OptionalInterfaceFactory::~OptionalInterfaceFactory ( ) [inline]

Class destructor.

Frees all interface instances constructed by this factory.


Member Function Documentation

Tp::OptionalInterfaceFactory::interfaces ( ) const [inline]

Return a list of interfaces supported by this object.

Returns:
List of supported interfaces.
bool Tp::OptionalInterfaceFactory::hasInterface ( const QString name) const [inline]
template<class Interface >
Interface* Tp::OptionalInterfaceFactory::optionalInterface ( InterfaceSupportedChecking  check = CheckInterfaceSupported) const [inline]
template<typename Interface >
template< typename Interface > inline Interface * Tp::OptionalInterfaceFactory::interface ( ) const [inline]

Return a pointer to a valid instance of a interface class, associated with the same remote object as the given main interface instance. The given main interface must be of the class the optional interface is generated for (for eg. ChannelInterfaceGroupInterface this means ChannelInterface) or a subclass.

First invocation of this method for a particular optional interface class will construct the instance; subsequent calls will return a pointer to the same instance.

The returned instance is freed when the factory is destroyed; using it after destroying the factory will likely produce a crash. As the instance is shared, it should not be freed directly.

Template Parameters:
InterfaceClass of the interface instance to get.
Returns:
A pointer to an optional interface instance.
void Tp::OptionalInterfaceFactory::setInterfaces ( const QStringList interfaces) [inline, protected]
