Detailed Description

Constructs Connection objects according to application-defined settings.

The ConnectionFactory class is used by Account and other classes which construct Account proxy instances to enable sharing instances of application-defined Connection subclasses with certain features always ready.


Constructor & Destructor Documentation

Tp::ConnectionFactory::~ConnectionFactory (  )  [virtual]

Class destructor.

Tp::ConnectionFactory::ConnectionFactory ( const QDBusConnection &  bus,
const Features features 
) [protected]

Class constructor.

As in create(), it should be noted that unlike Connection::becomeReady(), FeatureCore isn't assumed. If no features are specified, no Connection::becomeReady() call is made at all and the proxy won't be Connection::isReady().

Parameters:
bus The QDBusConnection for proxies constructed using this factory to use.
features The features to make ready on constructed Connections.

Member Function Documentation

ConnectionFactoryPtr Tp::ConnectionFactory::create ( const QDBusConnection &  bus,
const Features features = Features() 
) [static]

Creates a new ConnectionFactory.

Optionally, the features to make ready on all constructed proxies can be specified. The default is to make no features ready. It should be noted that unlike Connection::becomeReady(), FeatureCore isn't assumed. If no features are specified, which is the default behavior, no Connection::becomeReady() call is made at all and the proxy won't be Connection::isReady().

Parameters:
bus The QDBusConnection for proxies constructed using this factory to use.
features The features to make ready on constructed Connections.
Returns:
A pointer to the created factory.
PendingReady * Tp::ConnectionFactory::proxy ( const QString &  busName,
const QString &  objectPath,
const ChannelFactoryConstPtr chanFactory,
const ContactFactoryConstPtr contactFactory 
) const

Constructs a Connection proxy and begins making it ready.

If a valid proxy already exists in the factory cache for the given combination of busName and objectPath, it is returned instead. All newly created proxies are automatically cached until they're either DBusProxy::invalidated() or the last reference to them outside the factory has been dropped.

The proxy can be accessed immediately after this function returns using PendingReady::proxy(). The ready operation only finishes, however, when the features specified by features(), if any, are made ready as much as possible. If the service doesn't support a given feature, they won't obviously be ready even if the operation finished successfully, as is the case for Connection::becomeReady().

Parameters:
busName The bus/service name of the D-Bus connection object the proxy is constructed for.
objectPath The object path of the connection.
chanFactory The channel factory to use for the Connection.
contactFactory The channel factory to use for the Connection.
Returns:
A PendingReady operation with the proxy in PendingReady::proxy().
ConnectionPtr Tp::ConnectionFactory::construct ( const QString &  busName,
const QString &  objectPath,
const ChannelFactoryConstPtr chanFactory,
const ContactFactoryConstPtr contactFactory 
) const [protected, virtual]

Can be used by subclasses to override the Connection subclass constructed by the factory.

This is automatically called by proxy() to construct proxy instances if no valid cached proxy is found.

The default implementation constructs Tp::Connection objects.

Parameters:
busName The bus/service name of the D-Bus Connection object the proxy is constructed for.
objectPath The object path of the connection.
chanFactory The channel factory to use for the Connection.
contactFactory The channel factory to use for the Connection.
Returns:
A pointer to the constructed proxy.
QString Tp::ConnectionFactory::finalBusNameFrom ( const QString &  uniqueOrWellKnown  )  const [protected, virtual]

Transforms well-known names to the corresponding unique names, as is appropriate for Connection

Parameters:
uniqueOrWellKnown The name to transform.
Returns:
The unique name corresponding to uniqueOrWellKnown (which may be it itself).

Implements Tp::DBusProxyFactory.
