## Member Function Documentation

static QLatin1String Tp::Client::ChannelInterfaceCaptchaAuthenticationInterface::staticInterfaceName | ( |  | ) |
| inlinestatic

Returns the name of the interface "org.freedesktop.Telepathy.Channel.Interface.CaptchaAuthentication1", which this class represents.

Returns
  The D-Bus interface name.

Tp::PendingVariant* Tp::Client::ChannelInterfaceCaptchaAuthenticationInterface::requestPropertyCanRetryCaptcha | ( |  | ) | const
| inline

Asynchronous getter for the remote object property `CanRetryCaptcha` of type `bool`.

If true, GetCaptchas() can be expected to return new captcha information when in the Local_Pending state. If false, GetCaptchas() will return NotAvailable on subsequent calls.

Refreshing the captcha isn't required to work, although some protocols and implementations allow it. This is usually done in case a given captcha is unintelligible.

Returns
  A pending variant which will emit finished when the property has been retrieved.

Tp::PendingVariant* Tp::Client::ChannelInterfaceCaptchaAuthenticationInterface::requestPropertyCaptchaStatus | ( |  | ) | const
| inline

Asynchronous getter for the remote object property `CaptchaStatus` of type `uint`.

The current status of this channel.

Because only the Handler should call methods on this interface, the Handler MAY reduce round-trips by not fetching the initial value of this property, and instead assume that is initially Local_Pending.

This assumption normally avoids the need to call GetAll(), since the values of CaptchaError and CaptchaErrorDetails are also implied by this assumption, and the only other property is CanRetryCaptcha , which is immutable.

Returns
  A pending variant which will emit finished when the property has been retrieved.

Tp::PendingVariant* Tp::Client::ChannelInterfaceCaptchaAuthenticationInterface::requestPropertyCaptchaError | ( |  | ) | const
| inline

Asynchronous getter for the remote object property `CaptchaError` of type `QString`.

The reason for the CaptchaStatus , or an empty string if the state is neither Try_Again nor Failed.

Typical values: "", Cancelled, AuthenticationFailed, CaptchaNotSupported

In particular, an ordinary authentication failure (as would be produced for an incorrect answer) SHOULD be represented by AuthenticationFailed, cancellation by the user's request SHOULD be represented by Cancelled, cancellation due to the inability to display the captcha to the user or otherwise answer it SHOULD be represented by CaptchaNotSupported, and cancellation by a local process due to inconsistent or invalid challenges from the server SHOULD be represented by ServiceConfused.

If this interface appears on a ChannelTypeServerAuthenticationInterface channel, and connection to the server fails with an authentication failure, this error code SHOULD be copied into the ConnectionInterface::ConnectionError() signal.

Returns
  A pending variant which will emit finished when the property has been retrieved.

Tp::PendingVariant* Tp::Client::ChannelInterfaceCaptchaAuthenticationInterface::requestPropertyCaptchaErrorDetails | ( |  | ) | const
| inline

Asynchronous getter for the remote object property `CaptchaErrorDetails` of type `QVariantMap`.

If CaptchaError is non-empty, any additional information about the last disconnection; otherwise, the empty map. The keys and values are the same as for the second argument of ConnectionInterface::ConnectionError() .

If this interface appears on a ChannelTypeServerAuthenticationInterface channel, and connection to the server fails with an authentication failure, these details SHOULD be copied into the ConnectionInterface::ConnectionError() signal.

Returns
  A pending variant which will emit finished when the property has been retrieved.

Tp::PendingVariantMap* Tp::Client::ChannelInterfaceCaptchaAuthenticationInterface::requestAllProperties | ( |  | ) | const
| inline

Request all of the DBus properties on the interface.

Returns
  A pending variant map which will emit finished when the properties have been retrieved.

QDBusPendingReply<Tp::CaptchaInfoList, uint, QString> Tp::Client::ChannelInterfaceCaptchaAuthenticationInterface::GetCaptchas | ( | int | timeout = `-1` | ) |
| inlineslot

Begins a call to the D-Bus method `GetCaptchas` on the remote object.

Gets information regarding each of the captcha methods available and which and how many need to be successfully answered

To call this method successfully, the state must be Local_Pending or Try_Again. If it is Local_Pending, it remains Local_Pending. If called more than once while in Local_Pending state, or if the state is Try_Again, this method fetches a new set of captcha challenges, if possible, and the state returns to Local_Pending.

For instance, you could call GetCaptchas again from Local_Pending state if the user indicates that they can't understand the initially-offered captcha.

This is a method, not a property, so that it can be used to fetch more than one set of captcha challenges, and so that change notification is not required. Only the Handler should call this method and calling GetAll would not reduce round-trips, so the usual reasons to prefer a property do not apply here.

Note that timeout is ignored as of now. It will be used once http://bugreports.qt.nokia.com/browse/QTBUG-11775 is fixed.

Parameters

  timeout | The timeout in milliseconds.

Returns

Information about each of the available captcha methods.

Returns

The number of captcha methods required to be answered in order to successfully complete this captcha challenge (most frequently 1, but XMPP allows servers to demand that more than one captcha is answered).

Returns

The language of each Label in Captcha_Info if available, for instance en_US, or "" if unknown.

QDBusPendingReply<QByteArray> Tp::Client::ChannelInterfaceCaptchaAuthenticationInterface::GetCaptchaData | ( | uint | ID,
|  | const QString & | mimeType,
|  | int | timeout = `-1`
| ) |  |
| inlineslot

Begins a call to the D-Bus method `GetCaptchaData` on the remote object.

Fetch and return the captcha data. In protocols where captchas are downloaded out-of-band (for instance via HTTP), the connection manager is expected to do so.

Returns an empty array if the type was "qa"

If audio-based and image-based captchas are both available, we don't want to waste time downloading the audio until/unless the user asks to hear it. The extra D-Bus round-trips are not a problem, since they are expected to be quick compared with the time taken for the user to solve the captcha.

Note that timeout is ignored as of now. It will be used once http://bugreports.qt.nokia.com/browse/QTBUG-11775 is fixed.

Parameters

  ID |
      The ID of the captcha of which to retrieve data.
  mimeType |
      MIME type picked by the Handler, chosen from the list of MIME types
      received in GetCaptchas. XEP-0158 allows the same captcha to be
      made available in multiple formats, for instance the same spoken
      question as audio/x-wav, application/ogg and audio/speex.
  timeout | The timeout in milliseconds.

Returns

      Captcha data as requested.

QDBusPendingReply Tp::Client::ChannelInterfaceCaptchaAuthenticationInterface::AnswerCaptchas | ( | const Tp::CaptchaAnswers & | answers,
|  | int | timeout = `-1`
| ) |  |
| inlineslot

Begins a call to the D-Bus method `AnswerCaptchas` on the remote object.

Answer as many captchas as desired and/or required.

Callable in state Local_Pending only. State changes to Remote_Pending.

Note that timeout is ignored as of now. It will be used once http://bugreports.qt.nokia.com/browse/QTBUG-11775 is fixed.

Parameters

  answers |
      The mapping of captcha IDs to answer strings.
  timeout | The timeout in milliseconds.

QDBusPendingReply Tp::Client::ChannelInterfaceCaptchaAuthenticationInterface::CancelCaptcha | ( | uint | reason,
|  | const QString & | debugMessage,
|  | int | timeout = `-1`
| ) |  |
| inlineslot

Begins a call to the D-Bus method `CancelCaptcha` on the remote object.

Cancel. State changes to Failed with error NotAvailable or Cancelled if it isn't already Failed. All you can do now is to close the channel.

Note that timeout is ignored as of now. It will be used once http://bugreports.qt.nokia.com/browse/QTBUG-11775 is fixed.

Parameters

  reason |
      Reason for cancelling. This MAY be used to choose an error response
      to the remote server, and SHOULD also be reflected in the
      CaptchaError.
  debugMessage |
      A textual description of the reason for cancelling, supplied by the
      Handler. This message SHOULD NOT be sent to the remote server, but
      SHOULD be copied into the &apos;debug-message&apos; field of the
      CaptchaErrorDetails and ConnectionError.
  timeout | The timeout in milliseconds.
