Description

A channel factory is attached to a connection. It carries out channel requests from the connection, and responds to channel-related events on the underlying network connection (e.g. incoming calls).

Deprecated since version 0.11.7. Use TpChannelManager, a newer interface which can be used to implement modern D-Bus APIs, instead.

Signature of an implementation of RequestChannel.

Deprecated since version 0.11.7. Use TpChannelManager instead.

self :

 An object implementing TpChannelFactoryIface

chan_type :

 The channel type, e.g. TP_IFACE_CHANNEL_TYPE_TEXT

handle_type :

 The handle type of the channel's associated handle, or 0 if the channel has no associated handle

handle :

 The channel's associated handle, of type handle_type, or 0 if the channel has no associated handle

request :

 An opaque data structure representing the channel request; if this request is satisfied by a newly created channel, this structure MUST be included in the new-channel signal if the newly created channel has handle 0, and MAY be included in the signal if the newly created channel has nonzero handle.

ret :

 Set to the new channel if it is available immediately, as documented in the description of TpChannelFactoryRequestStatus

error :

 Set to the error if the return is TP_CHANNEL_FACTORY_REQUEST_STATUS_ERROR, unset otherwise

Returns :

 one of the values of TpChannelFactoryRequestStatus, and behaves as documented for that return value

Warning

TpChannelFactoryRequestStatus is deprecated and should not be used in newly-written code. 0.11.7

Indicates the result of a channel request.

Deprecated since version 0.11.7. Use TpChannelManager instead.

TP_CHANNEL_FACTORY_REQUEST_STATUS_NOT_IMPLEMENTED

 Same as the Telepathy error NotImplemented. The connection will try the next factory in its list; if all return this, the overall result of the request will be NotImplemented. *ret and *error are not set

TP_CHANNEL_FACTORY_REQUEST_STATUS_NOT_AVAILABLE

 Same as the Telepathy error NotAvailable. *ret and *error are not set

TP_CHANNEL_FACTORY_REQUEST_STATUS_INVALID_HANDLE

 Same as the Telepathy error InvalidHandle. *ret and *error are not set

TP_CHANNEL_FACTORY_REQUEST_STATUS_ERROR

 An error other than the above. *ret is not set, *error is set

TP_CHANNEL_FACTORY_REQUEST_STATUS_CREATED

 A new channel was created (possibly in response to more than one request). new-channel has already been emitted and *ret is set to the new channel.

TP_CHANNEL_FACTORY_REQUEST_STATUS_QUEUED

 A new channel will be created, or was created but is not ready yet. Either new-channel or channel-error will be emitted later. *ret and *error are not set.

TP_CHANNEL_FACTORY_REQUEST_STATUS_EXISTING

 An existing channel satisfies the request: new-channel was not emitted. *ret is set to the existing channel.

 Call func(channel, data) for each channel managed by this factory. Must be filled in by implementations.
