- <p>This interface exists to support channels where
- <tp:dbus-ref
- namespace="org.freedesktop.Telepathy">Channel.Close</tp:dbus-ref>
- is insufficiently destructive. At the moment this means
- <tp:dbus-ref
- namespace="org.freedesktop.Telepathy">Channel.Type.Text</tp:dbus-ref>,
- but the existence of this interface means that unsupported channels
- can be terminated in a non-channel-type-specific way.</p>
- </tp:docstring>
-
- <method name="Destroy" tp:name-for-bindings="Destroy">
- <tp:docstring xmlns="http://www.w3.org/1999/xhtml">
- <p>Close the channel abruptly, possibly with loss of data. The
- connection manager MUST NOT re-create the channel unless/until
- more events occur.</p>
-
- <tp:rationale>
- <p>The main motivating situation for this method is that when a Text
- channel with pending messages is closed with Close, it comes back
- as an incoming channel (to avoid a race between Close and an
- incoming message). If Destroy is called on a Text channel, the CM
- should delete all pending messages and close the channel, and
- the channel shouldn't be re-created until/unless another message
- arrives.</p>
- </tp:rationale>
-
- <p>Most clients SHOULD call
- <tp:dbus-ref
- namespace="org.freedesktop.Telepathy">Channel.Close</tp:dbus-ref>
- instead. However, if a client explicitly intends to destroy the
- channel with possible loss of data, it SHOULD call this method
- if this interface is supported (according to the
- <tp:dbus-ref
- namespace="org.freedesktop.Telepathy">Channel.Interfaces</tp:dbus-ref>
- property), falling back to Close if not.</p>
-
- <p>In particular, channel dispatchers SHOULD use this method if
- available when terminating channels that cannot be handled
- correctly (for instance, if no handler has been installed for
- a channel type, or if the handler crashes repeatedly).</p>
-
- <p>Connection managers do not need to implement this interface on
- channels where Close and Destroy would be equivalent.</p>
-
- <tp:rationale>
- <p>Callers need to be able to fall back to Close in any case.</p>
- </tp:rationale>
