connection | Connection owning this channel, and specifying the service. | |
objectPath | The channel object path. | |
immutableProperties | The channel immutable properties. | |
coreFeature | The core feature of the channel type, if any. The corresponding introspectable should depend on StreamedMediaChannel::FeatureCore. |
StreamedMediaChannelPtr Tp::StreamedMediaChannel::create | ( | const ConnectionPtr & | connection, | |

connection | Connection owning this channel, and specifying the service. | |
objectPath | The channel object path. | |
immutableProperties | The channel immutable properties. |
Reimplemented from Tp::Channel.
bool Tp::StreamedMediaChannel::awaitingLocalAnswer | ( | ) | const |
Return whether this channel is awaiting local answer.
This method requires StreamedMediaChannel::FeatureCore to be ready.
true
if awaiting local answer, false
otherwise.bool Tp::StreamedMediaChannel::awaitingRemoteAnswer | ( | ) | const |
Return whether this channel is awaiting remote answer.
This method requires StreamedMediaChannel::FeatureCore to be ready.
true
if awaiting remote answer, false
otherwise.PendingOperation * Tp::StreamedMediaChannel::acceptCall | ( | ) |
Accept an incoming call.
This method requires StreamedMediaChannel::FeatureCore to be ready.
PendingOperation * Tp::StreamedMediaChannel::hangupCall | ( | ) |
Request that the call is ended.
This method requires StreamedMediaChannel::FeatureCore to be ready.
StreamedMediaStreams Tp::StreamedMediaChannel::streams | ( | ) | const |
Return a list of media streams in this channel.
This methods requires StreamedMediaChannel::FeatureStreams to be ready.
StreamedMediaStreams Tp::StreamedMediaChannel::streamsForType | ( | MediaStreamType | type | ) | const |
Return a list of media streams in this channel for the given type type.
This methods requires StreamedMediaChannel::FeatureStreams to be ready.
type | The interested type. |
PendingStreamedMediaStreams * Tp::StreamedMediaChannel::requestStream | ( | const ContactPtr & | contact, | |
MediaStreamType | type | |||
) |
Request that media streams be established to exchange the given type type of media with the given contact contact.
This methods requires StreamedMediaChannel::FeatureStreams to be ready.
PendingStreamedMediaStreams * Tp::StreamedMediaChannel::requestStreams | ( | const ContactPtr & | contact, | |
QList< MediaStreamType > | types | |||
) |
Request that media streams be established to exchange the given types types of media with the given contact contact.
This methods requires StreamedMediaChannel::FeatureStreams to be ready.
PendingOperation * Tp::StreamedMediaChannel::removeStream | ( | const StreamedMediaStreamPtr & | stream | ) |
Remove the specified media stream from this channel.
This methods requires StreamedMediaChannel::FeatureStreams to be ready.
stream | Media stream to remove. |
PendingOperation * Tp::StreamedMediaChannel::removeStreams | ( | const StreamedMediaStreams & | streams | ) |
Remove the specified media streams from this channel.
This methods requires StreamedMediaChannel::FeatureStreams to be ready.
streams | List of media streams to remove. |
bool Tp::StreamedMediaChannel::handlerStreamingRequired | ( | ) | const |
Check whether media streaming by the handler is required for this channel.
For channels with the TP_QT4_IFACE_CHANNEL_INTERFACE_MEDIA_SIGNALLING interface, the main handler of the channel is responsible for doing the actual streaming, for instance by calling createFarsightChannel(channel) from TelepathyQt4-Farsight library and using the telepathy-farsight API on the resulting TfChannel.
This method requires StreamedMediaChannel::FeatureCore to be ready.
true
if required, false
otherwise.LocalHoldState Tp::StreamedMediaChannel::localHoldState | ( | ) | const |
Return the local hold state for this channel.
Whether the local user has placed this channel on hold.
This method requires StreamedMediaChannel::FeatureHoldState to be ready.
LocalHoldStateReason Tp::StreamedMediaChannel::localHoldStateReason | ( | ) | const |
Return the reason why localHoldState() changed to its current value.
This method requires StreamedMediaChannel::FeatureLocalHoldState to be ready.
PendingOperation * Tp::StreamedMediaChannel::requestHold | ( | bool | hold | ) |
Request that the channel be put on hold (be instructed not to send any media streams to you) or be taken off hold.
If the CM can immediately tell that the requested state change could not possibly succeed, the resulting PendingOperation will fail with error code TP_QT4_ERROR_NOT_AVAILABLE. If the requested state is the same as the current state, the resulting PendingOperation will finish successfully.
Otherwise, the channel's local hold state will change to LocalHoldStatePendingHold or LocalHoldStatePendingUnhold (as appropriate), then the resulting PendingOperation will finish successfully.
The eventual success or failure of the request is indicated by a subsequent localHoldStateChanged() signal, changing the local hold state to LocalHoldStateHeld or LocalHoldStateUnheld.
If the channel has multiple streams, and the connection manager succeeds in changing the hold state of one stream but fails to change the hold state of another, it will attempt to revert all streams to their previous hold states.
If the channel does not support the TP_QT4_IFACE_CHANNEL_INTERFACE_HOLD interface, the PendingOperation will fail with error code TP_QT4_ERROR_NOT_IMPLEMENTED.
hold | A boolean indicating whether or not the channel should be on hold |
void Tp::StreamedMediaChannel::streamAdded | ( | const Tp::StreamedMediaStreamPtr & | stream | ) | [signal] |

stream | The media stream that was added. |
void Tp::StreamedMediaChannel::streamRemoved | ( | const Tp::StreamedMediaStreamPtr & | stream | ) | [signal] |
Emitted when a media stream is removed from this channel.
stream | The media stream that was removed. |
void Tp::StreamedMediaChannel::streamDirectionChanged | ( | const Tp::StreamedMediaStreamPtr & | stream, | |
Tp::MediaStreamDirection | direction, | |||
Tp::MediaStreamPendingSend | pendingSend | |||
) | [signal] |
Emitted when a media stream direction changes.
stream | The media stream which the direction changed. | |
direction | The new direction of the stream that changed. | |
pendingSend | The new pending send flags of the stream that changed. |
void Tp::StreamedMediaChannel::streamStateChanged | ( | const Tp::StreamedMediaStreamPtr & | stream, | |
Tp::MediaStreamState | state | |||

void Tp::StreamedMediaChannel::streamError | ( | const Tp::StreamedMediaStreamPtr & | stream, | |
Tp::MediaStreamError | errorCode, | |||
const QString & | errorMessage | |||
) | [signal] |
void Tp::StreamedMediaChannel::localHoldStateChanged | ( | Tp::LocalHoldState | state, | |
Tp::LocalHoldStateReason | reason | |||

const Feature Tp::StreamedMediaChannel::FeatureCore [static] |
Feature representing the core that needs to become ready to make the StreamedMediaChannel object usable.
This is currently the same as Channel::FeatureCore, but may change to include more.
When calling isReady(), becomeReady(), this feature is implicitly added to the requested features.
Reimplemented from Tp::Channel.
const Feature Tp::StreamedMediaChannel::FeatureStreams [static] |
Feature used in order to access media stream specific methods.
See media stream specific methods' documentation for more details.
const Feature Tp::StreamedMediaChannel::FeatureLocalHoldState [static] |
Feature used in order to access local hold state info.
See local hold state specific methods' documentation for more details.
