Implemented Interfaces

InfcBrowser implements InfCommunicationObject and InfBrowser.

Includes

#include <libinfinity/client/infc-browser.h>

Description

The InfcBrowser is used to browse a remote directory and can be used to subscribe to sessions. InfcBrowser implements the InfBrowser interface, through which most operations are performed.

Functions

                  InfCommunicationManager *comm_manager,
                  InfXmlConnection *connection);

Creates a new InfcBrowser.

[constructor]

Parameters

io

A InfIo object used to schedule timeouts.

 

comm_manager

A InfCommunicationManager to register the server connection and which forwards incoming data to the browser or running sessions.

 

connection

Connection to the server.

 

Returns

A new InfcBrowser.

                               (InfcBrowser *browser);

Returns the communication manager of this browser.

Parameters

browser

A InfcBrowser.

 

Returns

A InfCommunicationManager.

infc_browser_get_connection ()

InfXmlConnection *
infc_browser_get_connection (InfcBrowser *browser);

Returns the connection to the server.

Parameters

A InfcBrowser.

 

Returns

A InfXmlConnection.

infc_browser_add_plugin ()

gboolean
infc_browser_add_plugin (InfcBrowser *browser,
                         const InfcNotePlugin *plugin);

Adds plugin to browser . This allows the browser to create sessions of the plugin's type. Only one plugin of each type can be added to the directory.

Parameters

browser

A InfcBrowser.

 

plugin

A InfcNotePlugin.

 

Returns

Whether the plugin was added successfully.

[transfer none]


infc_browser_lookup_plugin ()

const InfcNotePlugin *
infc_browser_lookup_plugin (InfcBrowser *browser,
                            const gchar *note_type);

Returns a previously registered plugin (see infc_browser_add_plugin()) for the given note type, or NULL if there is no such plugin.

Parameters

browser

A InfcBrowser.

 

note_type

A note type, such as "InfText".

 

Returns

A InfcNotePlugin, or NULL.

infc_browser_iter_save_session ()

InfRequest *
infc_browser_iter_save_session (InfcBrowser *browser,
                                const InfBrowserIter *iter,
                                InfRequestFunc func,
                                gpointer user_data);

Requests that the server saves the note pointed to by iter into its background storage. Normally, the server only does this when it is either shut down or when the there are no more subscriptions to the note. Note that this is merely a request and the server might decide not to save the session for whatever reason.

The request might either finish during the call to this function, in which case func will be called and NULL being returned. If the request does not finish within the function call, a InfRequest object is returned, where func has been installed for the “finished” signal, so that it is called as soon as the request finishes.

Parameters

browser

A InfcBrowser.

 

iter

A InfBrowserIter pointing to a note in browser .

 

func

The function to be called when the request finishes, or NULL.

[scope async]

user_data

Additional data to pass to func .

 

Returns

A InfRequest that may be used to get notified when the request finishes or fails.

infc_browser_iter_get_sync_in ()

InfcSessionProxy *
infc_browser_iter_get_sync_in (InfcBrowser *browser,
                               const InfBrowserIter *iter);

Returns the InfcSessionProxy that is used to synchronize the note iter points to to the server. Such a node is created by inf_browser_add_note() with non-NULL session parameter. If the client is subscribed to this note, then this returns the same session as inf_browser_get_session(). However, it is possible that we synchronize this node to the server without being subscribed to it. In this case, this function returns the session that does the synchronization, while inf_browser_get_session() would return NULL.

Parameters

browser

A InfcBrowser.

 

iter

A InfBrowserIter pointing to a note in browser .

 

Returns

A InfcSessionProxy, or NULL if we are currently not synchronizing this node to the server.

infc_browser_iter_get_sync_in_requests ()

GSList *
infc_browser_iter_get_sync_in_requests
                               (InfcBrowser *browser,
                                const InfBrowserIter *iter);

Returns a list of all InfRequests created with inf_browser_add_note() with the node iter points to as parent. Such requests begin a synchronization to the server when they have finished.

Parameters

browser

A InfcBrowser.

 

iter

A InfBrowserIter pointing to a subdirectory node in browser .

 

Returns

A list of InfRequests. Free with g_slist_free() when done.

infc_browser_iter_is_valid ()

gboolean
infc_browser_iter_is_valid (InfcBrowser *browser,
                            const InfBrowserIter *iter);

Returns whether iter points to a valid node in browser . This is generally the case for any InfBrowserIter returned by one of the InfcBrowser functions, it gets invalid however as soon as the node it points to is removed.

Parameters

browser

A InfcBrowser.

 

iter

A InfBrowserIter.

 

Returns

Whether iter points to a node in browser .


infc_browser_subscribe_chat ()

InfRequest *
infc_browser_subscribe_chat (InfcBrowser *browser,
                             InfRequestFunc func,
                             gpointer user_data);

Attempts to subscribe to the server's chat. When the operation finishes infc_browser_get_chat_session() will return a InfcSessionProxy representing the chat session. It can be used to read the chat's content. The request can fail in case the server chat is disabled.

The request might either finish during the call to this function, in which case func will be called and NULL being returned. If the request does not finish within the function call, a InfRequest object is returned, where func has been installed for the “finished” signal, so that it is called as soon as the request finishes.

Parameters

browser

A InfcBrowser.

 

func

The function to be called when the request finishes, or NULL.

[scope async]

user_data

Additional data to pass to func .

 

Returns

A InfRequest that may be used to get notified when the request finishes or fails.

infc_browser_get_subscribe_chat_request ()

InfRequest *
infc_browser_get_subscribe_chat_request
                               (InfcBrowser *browser);

Returns the InfRequest that represests the request sent to the server which attempts to subscribe to its chat. If there is no such request running, then the function returns NULL. After such a request finishes, call infc_browser_get_chat_session() to get the InfcSessionProxy for the chat session. To initiate the request, call infc_browser_subscribe_chat().

Parameters

browser

A InfcBrowser.

 

Returns

A InfRequest, or NULL.

infc_browser_get_chat_session ()

InfcSessionProxy *
infc_browser_get_chat_session (InfcBrowser *browser);

Returns the InfcSessionProxy representing the running chat session if the local client is subscribed to it, or NULL otherwise.

Parameters

browser

A InfcBrowser.

 

Returns

A InfcSessionProxy for the chat, or NULL.
