TpBaseConnectionProc ()

void
(*TpBaseConnectionProc) (TpBaseConnection *self);

Signature of a virtual method on TpBaseConnection that takes no additional parameters and returns nothing.

TpBaseConnectionStartConnectingImpl ()

gboolean
(*TpBaseConnectionStartConnectingImpl)
                               (TpBaseConnection *self,
                                GError **error);

Signature of an implementation of the start_connecting method of TpBaseConnection.

On entry, the implementation may assume that it is in state NEW.

If TRUE is returned, the Connect D-Bus method succeeds; the implementation must either have already set the status to CONNECTED by calling tp_base_connection_change_status(), or have arranged for a status change to either state DISCONNECTED or CONNECTED to be signalled by calling tp_base_connection_change_status() at some later time. If the status is still NEW after returning TRUE, TpBaseConnection will automatically change it to CONNECTING for reason REQUESTED.

If FALSE is returned, the error will be raised from Connect as an exception. If the status is not DISCONNECTED after FALSE is returned, TpBaseConnection will automatically change it to DISCONNECTED with a reason appropriate to the error; NetworkError results in NETWORK_ERROR, PermissionDenied results in AUTHENTICATION_FAILED, and all other errors currently result in NONE_SPECIFIED.

All except the simplest connection managers are expected to implement this asynchronously, returning TRUE in most cases and changing the status to CONNECTED or DISCONNECTED later.

tp_base_connection_get_bus_name ()

const gchar *
tp_base_connection_get_bus_name (TpBaseConnection *self);

Return the bus name starting with TP_CONN_BUS_NAME_BASE that represents this connection on D-Bus.

The returned string belongs to the TpBaseConnection and must be copied by the caller if it will be kept.

If this connection has never been present on D-Bus (tp_base_connection_register() has never been called), return NULL instead.

Since: 0.19.1

tp_base_connection_get_object_path ()

const gchar *
tp_base_connection_get_object_path (TpBaseConnection *self);

Return the object path starting with TP_CONN_OBJECT_PATH_BASE that represents this connection on D-Bus.

The returned string belongs to the TpBaseConnection and must be copied by the caller if it will be kept.

If this connection has never been present on D-Bus (tp_base_connection_register() has never been called), return NULL instead.

Since: 0.19.1

tp_base_connection_register ()

gboolean
tp_base_connection_register (TpBaseConnection *self,

                             GError **error);

Make the connection object appear on the bus, returning the bus name and object path used. If TRUE is returned, the connection owns the bus name, and will release it when destroyed.

Since 0.11.11, bus_name and object_path may be NULL if the strings are not needed.

tp_base_connection_get_handles ()

TpHandleRepoIface *
tp_base_connection_get_handles (TpBaseConnection *self,
                                TpHandleType handle_type);

tp_base_connection_get_self_handle ()

TpHandle
tp_base_connection_get_self_handle (TpBaseConnection *self);

Returns the “self-handle” property, which is guaranteed not to be 0 once the connection has moved to the CONNECTED state.

[skip]

Since: 0.7.15

tp_base_connection_set_self_handle ()

void
tp_base_connection_set_self_handle (TpBaseConnection *self,
                                    TpHandle self_handle);

Sets the “self-handle” property. self_handle may not be 0 once the connection has moved to the CONNECTED state.

Since: 0.7.15

tp_base_connection_get_status ()

TpConnectionStatus
tp_base_connection_get_status (TpBaseConnection *self);

Return the status of this connection, as set by tp_base_connection_change_status() or similar functions like tp_base_connection_disconnect_with_dbus_error().

Like the corresponding D-Bus property, this method returns TP_CONNECTION_STATUS_DISCONNECTED in two situations: either the connection is newly-created (and has never emitted “status-changed”), or D-Bus clients have already been told that it has been destroyed (by the Disconnect D-Bus method, a failed attempt to connect, or loss of an established connection). Use tp_base_connection_is_destroyed() to distinguish between the two.

Since: 0.19.1

tp_base_connection_is_destroyed ()

gboolean
tp_base_connection_is_destroyed (TpBaseConnection *self);

Return whether this connection has already emitted the D-Bus signal indicating that it has been destroyed.

In particular, this can be used to distinguish between the two reasons why tp_base_connection_get_status() would return TP_CONNECTION_STATUS_DISCONNECTED: it will return FALSE if the connection is newly-created, and TRUE if the Disconnect D-Bus method has been called, an attempt to connect has failed, or an established connection has encountered an error.

Since: 0.19.1

tp_base_connection_check_connected ()

gboolean
tp_base_connection_check_connected (TpBaseConnection *self,
                                    GError **error);

Return whether this connection is fully active and connected. If it is not, raise TP_ERROR_DISCONNECTED.

This is equivalent to checking whether tp_base_connection_get_status() returns TP_CONNECTION_STATUS_CONNECTED; it is provided because methods on the connection often need to make this check, and return a GError if it fails.

Since: 0.19.1

tp_base_connection_change_status ()

void
tp_base_connection_change_status (TpBaseConnection *self,
                                  TpConnectionStatus status,
                                  TpConnectionStatusReason reason);

Change the status of the connection. The allowed state transitions are:

Before the transition to TP_CONNECTION_STATUS_CONNECTED, the implementation must have discovered the handle for the local user and passed it to tp_base_connection_set_self_handle().

Changing from NEW to CONNECTED is implemented by doing the transition from NEW to CONNECTING, followed by the transition from CONNECTING to CONNECTED; it's exactly equivalent to calling tp_base_connection_change_status for those two transitions one after the other.

Any other valid transition does the following, in this order:

To provide more details about what happened when moving to status TP_CONNECTION_STATUS_DISCONNECTED due to an error, consider calling tp_base_connection_disconnect_with_dbus_error() instead of this function.

Changed in 0.7.35: the self_handle member of TpBaseConnection was previously set to 0 at this stage. It now remains non-zero until the object is disposed.

                                TpConnectionStatusReason reason);

void
tp_base_connection_add_interfaces (TpBaseConnection *self,
                                   const gchar **interfaces);

Add some interfaces to the list supported by this Connection. If you're going to call this function at all, you must do so before moving to state CONNECTED (or DISCONNECTED); if you don't call it, only the set of interfaces always present (get_interfaces_always_present in TpBaseConnectionClass) will be supported.

Implements D-Bus method RequestHandles on interface org.freedesktop.Telepathy.Connection.

This was exported so subclasses could use it as a basis for their reimplementations, but reimplementing the method is now deprecated.

TP_BASE_CONNECTION_ERROR_IF_NOT_CONNECTED()

#define             TP_BASE_CONNECTION_ERROR_IF_NOT_CONNECTED(conn, context)

If conn is not in state TP_CONNECTION_STATUS_CONNECTED, complete the D-Bus method invocation context by raising the Telepathy error TP_ERROR_DISCONNECTED, and return from the current function (which must be void). For use in D-Bus method implementations.

Add token to the set of tokens for which this connection will emit “clients-interested” and “clients-uninterested”.

Emitted when a client becomes interested in any token that was added with tp_base_connection_add_possible_client_interest().

The "signal detail" is a GQuark representing token . Modules implementing an interface (Location, say) should typically connect to a detailed signal like "clients-interested::org.freedesktop.Telepathy.Connection.Interface.Location" rather than receiving all emissions of this signal.

As with “clients-interested”, the "signal detail" is a GQuark representing token .
