<a name="TpChannelManager.description"></a><h2>Description</h2>
<p>
A channel manager is attached to a connection. It carries out channel
requests from the connection, and responds to channel-related events on the
underlying network connection, for particular classes of channel (for
example, incoming and outgoing calls, respectively). It also tracks
currently-open channels of the relevant kinds.
</p>
<p>
The connection has an array of channel managers. In response to a call to
CreateChannel or RequestChannel, the channel request is offered to each
channel manager in turn, until one accepts the request. In a trivial
implementation there might be a single channel manager which handles all
requests and all incoming events, but in general, there will be multiple
channel managers handling different types of channel.
</p>
<p>
For example, at the time of writing, Gabble has a roster channel manager
which handles contact lists and groups, an IM channel manager which
handles one-to-one messaging, a MUC channel manager which handles
multi-user chat rooms, the index of chat rooms and MUC tubes, a media
channel manager which handles VoIP calls, and a 1-1 tubes channel manager.

Implementations should inspect the contents of <em class="parameter"><code>request_properties</code></em> to see if
it matches a channel class handled by this manager.  If so, they should

exactly one of the <a class="link" href="TpChannelManager.html#TpChannelManager-new-channels" title='The "new-channels" signal'><span class="type">"new-channels"</span></a>,

If the implementation does not want to handle the request, it should return
<code class="literal">FALSE</code> to allow the request to be offered to another channel manager.

Emitted when new channels have been created. The Connection should
generally emit NewChannels (and NewChannel) in response to this
signal, and then return from pending CreateChannel, EnsureChannel
and/or RequestChannel calls if appropriate.
</p>
<p>
Since 0.19.1, clients should not emit more than one
 channel in this signal at one time as the creation of
 multiple channels together in a single signal is strongly
 recommended against: it's very complicated, hard to get
 right in clients, and not nearly as useful as it originally
 sounded.
