/**
 * \class Account
 * \ingroup clientaccount
 * \headerfile TelepathyQt/account.h <TelepathyQt/Account>
 *
 * \brief The Account class represents a Telepathy account.
 *
 * The remote object accessor functions on this object (isValidAccount(),
 * isEnabled(), and so on) don't make any D-Bus calls; instead, they return/use
 * values cached from a previous introspection run. The introspection process
 * populates their values in the most efficient way possible based on what the
 * service implements.
 *
 * To avoid unnecessary D-Bus traffic, some accessors only return valid
 * information after specific features have been enabled.
 * For instance, to retrieve the account protocol information, it is necessary to
 * enable the feature Account::FeatureProtocolInfo.
 * See the individual methods descriptions for more details.
 *
 * Account features can be enabled by constructing an AccountFactory and enabling
 * the desired features, and passing it to AccountManager or ClientRegistrar
 * when creating them as appropriate. However, if a particular
 * feature is only ever used in a specific circumstance, such as an user opening
 * some settings dialog separate from the general view of the application,
 * features can be later enabled as needed by calling becomeReady() with the additional
 * features, and waiting for the resulting PendingOperation to finish.
 *
 * As an addition to accessors, signals are emitted to indicate that properties have
 * changed, for example displayNameChanged(), iconNameChanged(), etc.
 *
 * Convenience methods to create channels using the channel dispatcher such as
 * ensureTextChat(), createFileTransfer() are also provided.
 *
 * If the account is deleted from the AccountManager, this object
 * will not be deleted automatically; however, it will emit invalidated()
 * with error code #TP_QT_ERROR_OBJECT_REMOVED and will cease to
 * be useful.
 *
 * \section account_usage_sec Usage
 *
 * \subsection account_create_sec Creating an account object
 *
 * The easiest way to create account objects is through AccountManager. One can
 * just use the AccountManager convenience methods such as
 * AccountManager::validAccounts() to get a list of account objects representing
 * valid accounts.
 *
 * If you already know the object path, you can just call create().
 * For example:
 *
 * \code AccountPtr acc = Account::create(busName, objectPath); \endcode
 *
 * An AccountPtr object is returned, which will automatically keep
 * track of object lifetime.
 *
 * You can also provide a D-Bus connection as a QDBusConnection:
 *
 * \code
 *
 * AccountPtr acc = Account::create(QDBusConnection::sessionBus(),
 *         busName, objectPath);
 *
 * \endcode
 *
 * \subsection account_ready_sec Making account ready to use
 *
 * An Account object needs to become ready before usage, meaning that the
 * introspection process finished and the object accessors can be used.
 *
 * To make the object ready, use becomeReady() and wait for the
 * PendingOperation::finished() signal to be emitted.
 *
 * \code
 *
 * class MyClass : public QObject
 * {
 *     QOBJECT
 *
 * public:
 *     MyClass(QObject *parent = 0);
 *     ~MyClass() { }
 *
 * private Q_SLOTS:
 *     void onAccountReady(Tp::PendingOperation*);
 *
 * private:
 *     AccountPtr acc;
 * };
 *
 * MyClass::MyClass(const QString &busName, const QString &objectPath,
 *         QObject *parent)
 *     : QObject(parent)
 *       acc(Account::create(busName, objectPath))
 * {
 *     connect(acc->becomeReady(),
 *             SIGNAL(finished(Tp::PendingOperation*)),
 *             SLOT(onAccountReady(Tp::PendingOperation*)));
 * }
 *
 * void MyClass::onAccountReady(Tp::PendingOperation *op)
 * {
 *     if (op->isError()) {
 *         qWarning() << "Account cannot become ready:" <<
 *             op->errorName() << "-" << op->errorMessage();
 *         return;
 *     }
 *
 *     // Account is now ready
 *     qDebug() << "Display name:" << acc->displayName();
 * }
 *
 * \endcode
 *
 * See \ref async_model, \ref shared_ptr
