<p>The <a class="el" href="classTp_1_1AbstractClientObserver.html" title="The AbstractClientObserver class provides an object representing a Telepathy observer...">AbstractClientObserver</a> class provides an object representing a Telepathy observer. </p>
<p>Observers are clients that monitor the creation of new channels. This functionality can be used for things like message logging.</p>
<p>Observers should not modify the state of a channel except via user interaction.</p>
<p>Observers must not carry out actions that exactly one process must take responsibility for (e.g. acknowledging text messages, or carrying out the actual file transfer), since arbitrarily many observers can be activated for each channel. The handler is responsible for such tasks.</p>
<p>Handlers may, of course, delegate responsibility for these tasks to other clients (including those run as observers), but this must be done explicitly via a request from the handler to the observer.</p>
<p>Whenever a collection of new channels is signalled, the channel dispatcher will notify all running or activatable observers whose filter indicates that they are interested in some of the channels.</p>
<p>Observers are activated for all channels in which they have registered an interest - incoming, outgoing or automatically created - although of course the filter property can be set to filter specific channels.</p>
<p>To become an observer one should inherit <a class="el" href="classTp_1_1AbstractClientObserver.html" title="The AbstractClientObserver class provides an object representing a Telepathy observer...">AbstractClientObserver</a> and implement the pure virtual <a class="el" href="classTp_1_1AbstractClientObserver.html#a63c940820635ac64c5a321a90b9c2a1a">observeChannels()</a> method. After that the object representing the observer must be registered using <a class="el" href="classTp_1_1ClientRegistrar.html#a18c094053cc83809a167370f7113341b">ClientRegistrar::registerClient()</a>.</p>
<p>When new channels in which the observer has registered an interest are announced, the method <a class="el" href="classTp_1_1AbstractClientObserver.html#a63c940820635ac64c5a321a90b9c2a1a">observeChannels()</a> is invoked. All observers are notified simultaneously.</p>

<p>Return the property containing a specification of the channels that this channel observer is interested. The <a class="el" href="classTp_1_1AbstractClientObserver.html#a63c940820635ac64c5a321a90b9c2a1a">observeChannels()</a> method should be called by the channel dispatcher whenever any of the newly created channels match this description.</p>
<p>Only certain types have useful semantics for matching like this, so only certain types are allowed:</p>
<p>See <a href="http://telepathy.freedesktop.org/spec/org.freedesktop.Telepathy.Client.Observer.html#org.freedesktop.Telepathy.Client.Observer.ObserverChannelFilter">the Telepathy D-Bus API Specification</a> for documentation about the allowed types and how to define filters.</p>
<p>This property never changes while the observer process owns its client bus name. If an observer wants to add extra channels to its list of interests at runtime, it can register an additional client bus name using <a class="el" href="classTp_1_1ClientRegistrar.html#a18c094053cc83809a167370f7113341b">ClientRegistrar::registerClient()</a>. To remove those filters, it can release the bus name using <a class="el" href="classTp_1_1ClientRegistrar.html#a6bfe24179b1e9d44a6a618a0d346e4a7">ClientRegistrar::unregisterClient()</a>.</p>

<p>Called by the channel dispatcher when channels in which the observer has registered an interest are announced.</p>
<p>If the announced channels contains channels that match the <a class="el" href="classTp_1_1AbstractClientObserver.html#a573f7e277176df6adafa830a20ebadbe">observerChannelFilter()</a>, and some that do not, then only a subset of the channels (those that do match the filter) are passed to this method.</p>
<p>If the channel dispatcher will split up the channels from a single announcement and dispatch them separately (for instance because no installed handler can handle all of them), it will call this method several times.</p>
<p>The observer must not call <a class="el" href="classTp_1_1MethodInvocationContext.html#a178f52fefcc6ac93f1e9aef7c5c8b984">MethodInvocationContext::setFinished()</a> until it is ready for a handler for the channel to run (which may change the channel's state). For instance the received <em>context</em> object should be stored until this method is finished processing and then <a class="el" href="classTp_1_1MethodInvocationContext.html#a178f52fefcc6ac93f1e9aef7c5c8b984">MethodInvocationContext::setFinished()</a> or <a class="el" href="classTp_1_1MethodInvocationContext.html#accc180d53a757b3aa9bc9286dc464712">MethodInvocationContext::setFinishedWithError()</a> should be called on the received <em>context</em> object.</p>
<p>Specialized observers must reimplement this method.</p>
