Voice Use cases:
----------------
In JabberAccount:
-Account is connected:
* Init the JingleSessionManager (accessible via account()->jingleSessionManager())
* Add voice extension to client features.
* Connect to incomingSession(const QString &sessionType, JingleSession *session) signal in JabberAccount.
-On incoming session
* Create and show VoiceConversationDialog.
* VoiceConversationDialog will handle the communcation between the user and the session.
In JabberContact:
-User select "Start voice conversation..."
* Get the best resource that support voice. If no compatible resource is found, show a message box.
* Create a JingleVoiceSession using JingleVoiceSessionManager.
* Create VoiceConversationDialog
* and VoiceConversationDialog will handle the communication between the user and the session.
In VoiceConversationDialog:
-Incoming voice session
* Accept the session call JingleVoiceSession::accept();
* Decline the session call JingleVoiceSession::decline();
-Accepted voice session
* Change GUI to "Voice session in progress."
-On declining voice session or terminating a session.
* Remove JingleVoiceSession from JingleVoiceSessionManager.
* Close the dialog.
===================================================================================================
Design with future in mind. Only voice session type is available today, but others will come.
A session is a connection between two or multiple peers.
A session do not handle multiple "calls"(or whatever it called depending of the context). That's will be job of SessionManager
A sesson has a myself user and others users, all identified by their full JID. (maybe their JabberBaseContact or JabberResource object ?)
-Maybe use the Channel pattern, where Session will hold one or multiple Channels. Think for voice+video for example. ?
All manager classes must be unique for each account.
JidList = QValueList<XMPP::Jid> or QStringList if QValueList<XMPP::Jid> doesn't work.
JingleSession and derivated are created by the Manager class.
SessionType is the XML Namespace of the session type (ex: http://jabber.org/protocol/sessions/audio)
JingleSessionManager
--------------------
Manage Jingle sessions.
-Manage global (maybe static ?)objects shared by all sessions (cricket::BasicPortAllocator, cricket::SessionManager).
Has a JingleWatchSessionTask(derived from XMPP::Task) that check for incoming session in JingleSessionManager, that check the session type,
create the right JingleSession subclass, then emit the required signal. This bypass libjingle to have a better
control on incoming session request and avoid using multiple Manager for each session type.
JingleSessionManager manage the JingleSession pointers. Do not delete it in user classes.
* JingleSessionManager(JabberAccount *)
* public slots:
* JingleSession *createSession(const QString &sessionType, const JidList &peers);
* void removeSession(JingleSession *);
signals:
* void incomingSession(const QString &sessionType, JingleSession *session);
JingleSession
-------------
Base class for Jingle session. A session is a
* JingleSession(JingleSessionManager *manager, const JidList &peers);
* XMPP::Jid &myself(); // account()->client()->jid();
* JidList &peers();
* JabberAccount *account();
* JingleSessionManager *manager();
// Start the negociation phase.
* virtual void start() = 0;
// Send the IQ stanza with action "accept"
* virtual void accept() = 0;
// Send the IQ stanza with action "
* virtual void decline() = 0;
* virtual void terminate() = 0;
// Return Session XML namespace
* virtual QString sessionType() = 0;
protected slots:
void sendStanza(const QString &stanza) { account()->client->send(stanza);
signals:
void accepted();
void declined();
void terminated();
JingleVoiceSession : public JingleSession
------------------
Define a VoIP voice session between two peers(for the moment).
Hold the PhoneSessionClient object.
connect(account()->client(),SIGNAL(xmlIncoming(const QString&)),SLOT(receiveStanza(const QString&)));
private slots:
void receiveStanza(const QString &stanza);
VoiceConversationDialog
-----------------------
* VoiceConversationDialog(JingleVoiceSession *)
VoiceConversationDialog will handle the communcation between the user and a session.
Should auto-delete when closed.
It can:
-Accept a voice session.
-Decline a voice session.
-Terminate a voice session(or hang-up).
It is the Action menu that can start a session.
