Description

One of the channel dispatcher's functions is to offer incoming channels to Approver clients for approval. Approvers respond to the channel dispatcher via a TpChannelDispatchOperation object.

Functions

tp_channel_dispatch_operation_new ()

TpChannelDispatchOperation *
tp_channel_dispatch_operation_new (TpDBusDaemon *bus_daemon,
                                   const gchar *object_path,
                                   GHashTable *immutable_properties,
                                   GError **error);

tp_channel_dispatch_operation_new is deprecated and should not be used in newly-written code.

Since 0.19.9. New code should get TpChannelDispatchOperation objects from a TpBaseClient

Convenience function to create a new channel dispatch operation proxy.

The immutable_properties argument is not yet used.

Parameters

bus_daemon

Proxy for the D-Bus daemon

 

object_path

The non-NULL object path of this channel dispatch operation

 

immutable_properties

As many as are known of the immutable D-Bus properties of this channel dispatch operation, or NULL if none are known

 

error

Used to raise an error if NULL is returned

 

Returns

a new reference to an channel dispatch operation proxy, or NULL if object_path is not syntactically valid or the channel dispatcher is not running


tp_channel_dispatch_operation_init_known_interfaces ()

void
tp_channel_dispatch_operation_init_known_interfaces
                               (void);

Ensure that the known interfaces for TpChannelDispatchOperation have been set up. This is done automatically when necessary, but for correct overriding of library interfaces by local extensions, you should call this function before calling tp_proxy_or_subclass_hook_on_interface_add() with first argument TP_TYPE_CHANNEL_DISPATCH_OPERATION.

Since: 0.7.32


tp_cli_channel_dispatch_operation_callback_for_claim ()

tp_cli_channel_dispatch_operation_call_claim ()

TpProxyPendingCall *
tp_cli_channel_dispatch_operation_call_claim
                               (TpChannelDispatchOperation *proxy,
                                gint timeout_ms,
                                tp_cli_channel_dispatch_operation_callback_for_claim callback,

                                GObject *weak_object);

Start a Claim method call.

<tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>Called by an approver to claim channels for handling internally. If this method is called successfully, the process calling this method becomes the handler for the channel, but <em>does not</em> have the <tp:dbus-ref namespace="org.freedesktop.Telepathy.Client.Handler">HandleChannels</tp:dbus-ref> method called on it.</p> <p>Clients that call Claim on channels but do not immediately close them SHOULD implement the Handler interface and its <tp:dbus-ref namespace="org.freedesktop.Telepathy.Client.Handler">HandledChannels</tp:dbus-ref> property.</p> <p>Approvers wishing to reject channels MUST call this method to claim ownership of them, and MUST NOT call <tp:dbus-ref namespace="org.freedesktop.Telepathy.Channel">Close</tp:dbus-ref> on the channels unless/until this method returns successfully.</p> <tp:rationale> <p>The channel dispatcher can't know how best to close arbitrary channel types, so it leaves it up to the approver to do so. For instance, for Text channels it is necessary to acknowledge any messages that have already been displayed to the user first - ideally, the approver would display and then acknowledge the messages - or to call <tp:dbus-ref namespace="org.freedesktop.Telepathy">Channel.Interface.Destroyable.Destroy</tp:dbus-ref> if the destructive behaviour of that method is desired.</p> <p>Similarly, an Approver for StreamedMedia channels can close the channel with a reason (e.g. &quot;busy&quot;) if desired. The channel dispatcher, which is designed to have no specific knowledge of particular channel types, can't do that.</p> </tp:rationale> <p>If successful, this method will cause the ChannelDispatchOperation object to disappear, emitting <tp:member-ref>Finished</tp:member-ref>, in the same way as for <tp:member-ref>HandleWith</tp:member-ref>.</p> <p>This method may fail because the dispatch operation has already been completed. Again, see HandleWith for more details. The approver MUST NOT attempt to interact with the channels further in this case.</p> <p>(FIXME: list some other possible errors)</p>

Parameters

proxy

the TpProxy

 

timeout_ms

the timeout in milliseconds, or -1 to use the default

 

callback

called when the method call succeeds or fails; may be NULL to make a "fire and forget" call with no reply tracking

 

user_data

user-supplied data passed to the callback; must be NULL if callback is NULL

 

destroy

called with the user_data as argument, after the call has succeeded, failed or been cancelled; must be NULL if callback is NULL

 

weak_object

If not NULL, a GObject which will be weakly referenced; if it is destroyed, this call will automatically be cancelled. Must be NULL if callback is NULL

 

Returns

a TpProxyPendingCall representing the call in progress. It is borrowed from the object, and will become invalid when the callback is called, the call is cancelled or the TpProxy becomes invalid.

Start a HandleWith method call.

<tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>Called by an approver to accept a channel bundle and request that the given handler be used to handle it.</p> <p>If successful, this method will cause the ChannelDispatchOperation object to disappear, emitting <tp:member-ref>Finished</tp:member-ref>.</p> <p>However, this method may fail because the dispatch has already been completed and the object has already gone. If this occurs, it indicates that another approver has asked for the bundle to be handled by a particular handler. The approver MUST NOT attempt to interact with the channels further in this case, unless it is separately invoked as the handler.</p> <p>Approvers which are also channel handlers SHOULD use <tp:member-ref>Claim</tp:member-ref> instead of HandleWith to request that they can handle a channel bundle themselves.</p> <p>(FIXME: list some possible errors)</p> <p>If the channel handler raises an error from <tp:dbus-ref namespace="org.freedesktop.Telepathy.Client.Handler">HandleChannels</tp:dbus-ref>, this method MAY respond by raising that same error, even if it is not specifically documented here.</p>

Connect a handler to the signal ChannelLost.

<tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>A channel has closed before it could be claimed or handled. If this is emitted for the last remaining channel in a channel dispatch operation, it MUST immediately be followed by <tp:member-ref>Finished</tp:member-ref>.</p> <p>This signal MUST NOT be emitted until all Approvers that were invoked have returned (successfully or with an error) from their <tp:dbus-ref namespace="org.freedesktop.Telepathy.Client.Approver">AddDispatchOperation</tp:dbus-ref> method.</p> <tp:rationale> <p>This means that Approvers can connect to the ChannelLost signal in a race-free way. Non-approver processes that discover a channel dispatch operation in some way (such as observers) will have to follow the usual &quot;connect to signals then recover state&quot; model - first connect to ChannelLost and <tp:member-ref>Finished</tp:member-ref>, then download <tp:member-ref>Channels</tp:member-ref> (and on error, perhaps assume that the operation has already Finished).</p> </tp:rationale>

Parameters

error

If not NULL, used to raise an error if NULL is returned

 

Returns

a TpProxySignalConnection containing all of the above, which can be used to disconnect the signal; or NULL if the proxy does not have the desired interface or has become invalid.

tp_channel_dispatch_operation_handle_with_async ()

void
tp_channel_dispatch_operation_handle_with_async
                               (TpChannelDispatchOperation *self,
                                const gchar *handler,
                                GAsyncReadyCallback callback,
                                gpointer user_data);

Called by an approver to accept a channel bundle and request that the given handler be used to handle it.

If successful, this method will cause the “invalidated” signal to be emitted with the TP_DBUS_ERROR_OBJECT_REMOVED error code.

However, this method may fail because the dispatch has already been completed and the object has already gone. If this occurs, it indicates that another approver has asked for the bundle to be handled by a particular handler. The approver MUST NOT attempt to interact with the channels further in this case, unless it is separately invoked as the handler.

Approvers which are also channel handlers SHOULD use tp_channel_dispatch_operation_claim_async() instead of tp_channel_dispatch_operation_handle_with_async() to request that they can handle a channel bundle themselves.

Parameters

self

a TpChannelDispatchOperation

 

handler

The well-known bus name (starting with TP_CLIENT_BUS_NAME_BASE) of the channel handler that should handle the channel, or NULL if the client has no preferred channel handler.

[allow-none]

callback

a callback to call when the call returns

 

user_data

data to pass to callback

                                gpointer user_data);

A variant of tp_channel_dispatch_operation_handle_with_async() allowing the approver to pass an user action time. This timestamp will be passed to the Handler when HandleChannels is called.

If an X server timestamp for the user action causing this method call is available, user_action_time should be this timestamp (for instance, the result of gdk_event_get_time() if it is not GDK_CURRENT_TIME). Otherwise, it may be TP_USER_ACTION_TIME_NOT_USER_ACTION to behave as if there was no user action or it happened a long time ago, or TP_USER_ACTION_TIME_CURRENT_TIME to have the Handler behave as though the user action had just happened (resembling, but not numerically equal to, GDK_CURRENT_TIME).

This method has been introduced in telepathy-mission-control 5.5.0.

Parameters

self

a TpChannelDispatchOperation

 

handler

The well-known bus name (starting with TP_CLIENT_BUS_NAME_BASE) of the channel handler that should handle the channel, or NULL if the client has no preferred channel handler.

[allow-none]

user_action_time

the time at which user action occurred, or one of the special values TP_USER_ACTION_TIME_NOT_USER_ACTION or TP_USER_ACTION_TIME_CURRENT_TIME

Types and Values

struct TpChannelDispatchOperation

struct TpChannelDispatchOperation;

One of the channel dispatcher's functions is to offer incoming channels to Approver clients for approval. An approver should generally ask the user whether they want to participate in the requested communication channels (join the chat or chatroom, answer the call, accept the file transfer, or whatever is appropriate). A collection of channels offered in this way is represented by a ChannelDispatchOperation object.

If the user wishes to accept the communication channels, the approver should call tp_cli_channel_dispatch_operation_call_handle_with() to indicate the user's or approver's preferred handler for the channels (the empty string indicates no particular preference, and will cause any suitable handler to be used).

If the user wishes to reject the communication channels, or if the user accepts the channels and the approver will handle them itself, the approver should call tp_cli_channel_dispatch_operation_call_claim(). If this method succeeds, the approver immediately has control over the channels as their primary handler, and may do anything with them (in particular, it may close them in whatever way seems most appropriate).

There are various situations in which the channel dispatch operation will be closed, causing the “invalidated” signal to be emitted. If this happens, the approver should stop prompting the user.

Because all approvers are launched simultaneously, the user might respond to another approver; if this happens, the “invalidated” signal will be emitted with the domain TP_DBUS_ERRORS and the error code TP_DBUS_ERROR_OBJECT_REMOVED.

If a channel closes, the “channel-lost” signal is emitted. If all channels close, there is nothing more to dispatch, so the “invalidated” signal will be emitted with the domain TP_DBUS_ERRORS and the error code TP_DBUS_ERROR_OBJECT_REMOVED.

If the channel dispatcher crashes or exits, the “invalidated” signal will be emitted with the domain TP_DBUS_ERRORS and the error code TP_DBUS_ERROR_NAME_OWNER_LOST. In a high-quality implementation, the dispatcher should be restarted, at which point it will create new channel dispatch operations for any undispatched channels, and the approver will be notified again.

Creating a TpChannelDispatchOperation directly is deprecated: it should only be created via a TpBaseClient.

Since 0.16, TpChannelDispatchOperation always has a non-NULL “factory”, which will be propagated to the TpAccount, TpConnection and TpChannel.

Since: 0.7.32


struct TpChannelDispatchOperationClass

struct TpChannelDispatchOperationClass {
};

The class of a TpChannelDispatchOperation.


TP_CHANNEL_DISPATCH_OPERATION_FEATURE_CORE

#define             TP_CHANNEL_DISPATCH_OPERATION_FEATURE_CORE

Expands to a call to a function that returns a quark for the "core" feature on a TpChannelDispatchOperation.

When this feature is prepared, the basic properties of the ChannelDispatchOperation have been retrieved and are available for use.

Specifically, this implies that:

  • “connection” is set (but TP_CONNECTION_FEATURE_CORE is not necessarily prepared)

  • “account” is set (but TP_ACCOUNT_FEATURE_CORE is not necessarily prepared)

  • “channels” is set (but TP_CHANNEL_FEATURE_CORE is not necessarily prepared)

  • “possible-handlers” is set

  • any extra interfaces will have been set up in TpProxy (i.e. “interfaces” contains at least all extra ChannelDispatchOperation interfaces)

One can ask for a feature to be prepared using the tp_proxy_prepare_async() function, and waiting for it to callback.
