<h2>Group interface</h2>
<p><a class="anchor" id="amgrp02d0efcc02d2acd5240d87f067046f11"></a> Cached access to state of the group interface on the associated remote object, if the interface is present. Almost all methods return undefined values if the list returned by <a class="el" href="classTp_1_1OptionalInterfaceFactory.html#afa2877d62298299d006b46d77fecc09e">interfaces()</a> doesn't include TELEPATHY_INTERFACE_CHANNEL_INTERFACE_GROUP or if the object is not ready.</p>
<p>Some methods can be used when <a class="el" href="classTp_1_1Channel.html#a46a3061648e781c3c363ef5285197786">targetHandleType()</a> == HandleTypeContact, such as <a class="el" href="classTp_1_1Channel.html#a9dd3e6cec14ed14123ffe1bdb3acb0a9">groupFlags()</a>, <a class="el" href="classTp_1_1Channel.html#a6cb2dbd3acece5a370c7ab99b80f34e6">groupCanAddContacts()</a>, <a class="el" href="classTp_1_1Channel.html#a5c5490d743c142adf8d5703e2ed6c2d0">groupCanRemoveContacts()</a>, <a class="el" href="classTp_1_1Channel.html#abff3edca07f40572b69ab1eb40b6b160">groupSelfContact()</a> and <a class="el" href="classTp_1_1Channel.html#a5e67eae020dbc225fda66c2fec4d33c7">groupContacts()</a>.</p>
<p>As the Group interface state can change freely during the lifetime of the channel due to events like new contacts joining the group, the cached state is automatically kept in sync with the remote object's state by hooking to the change notification signals present in the D-Bus interface.</p>
<p>As the cached value changes, change notification signals are emitted.</p>
<p>Signals are emitted to indicate that properties have changed, for <a class="el" href="classTp_1_1Channel.html#a9a19634088f78c3fb81fd166df72739e">groupMembersChanged()</a>, <a class="el" href="classTp_1_1Channel.html#af49ad76277e06b7ebf82e1577275a483">groupSelfContactChanged()</a>, etc.</p>
<p>Check the individual signals' descriptions for details. </p>

<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>The <a class="el" href="classTp_1_1Channel.html" title="The Channel class provides an object representing a Telepathy channel.">Channel</a> class provides an object representing a Telepathy channel. </p>
<p>All communication in the Telepathy framework is carried out via channel objects which are created and managed by connections. Specialized classes for some specific channel types such as <a class="el" href="classTp_1_1StreamedMediaChannel.html" title="The StreamedMediaChannel class provides an object representing a Telepathy channel...">StreamedMediaChannel</a>, <a class="el" href="classTp_1_1TextChannel.html" title="The TextChannel class provides an object representing a Telepathy channel of type...">TextChannel</a>, <a class="el" href="classTp_1_1FileTransferChannel.html" title="The FileTransferChannel class provides an object representing a Telepathy channel...">FileTransferChannel</a> are provided.</p>
<p>It adds the following features compared to using Client::ChannelInterface directly: </p>
<ul>
<li>
Life cycle tracking </li>
<li>
Getting the channel type, handle type, handle and interfaces automatically </li>
<li>
High-level methods for the Group/Conference/MergeableConference/Splittable interfaces </li>
<li>
A fake group implementation when handle type is HandleTypeContact </li>
</ul>
<p>The remote object state accessor functions on this object (<a class="el" href="classTp_1_1OptionalInterfaceFactory.html#afa2877d62298299d006b46d77fecc09e">interfaces()</a>, <a class="el" href="classTp_1_1Channel.html#a9bbf9b2886d305548677d8821a34bd50">channelType()</a>, <a class="el" href="classTp_1_1Channel.html#a46a3061648e781c3c363ef5285197786">targetHandleType()</a>, <a class="el" href="classTp_1_1Channel.html#a799b68a6d9a24aa4433e95baeb54cc12">targetHandle()</a>, requested(), <a class="el" href="classTp_1_1Channel.html#ae283517935f22e7a21853de03c889ff7">initiatorContact()</a>, and so on) don't make any D-Bus calls; instead, they return/use values cached from a previous introspection run. The introspection process populates their values in the most efficient way possible based on what the service implements. Their return value is mostly undefined until the introspection process is completed, i.e. <a class="el" href="classTp_1_1ReadyObject.html#a344fc63eaef5278cbf938eaa1ed4c635">isReady()</a> returns true. See the individual accessor descriptions for more details.</p>
<p>Additionally, the state of the group interface on the remote object (if present) will be cached in the introspection process, and also tracked for any changes.</p>
<p>To avoid unnecessary D-Bus traffic, some methods only return valid information after a specific feature has been enabled by calling <a class="el" href="classTp_1_1ReadyObject.html#ac02393f99a46725a4ffee32caaec13cc">becomeReady()</a> with the desired set of features as an argument, and waiting for the resulting <a class="el" href="classTp_1_1PendingOperation.html" title="Abstract base class for pending asynchronous operations.">PendingOperation</a> to finish. For instance, to retrieve the initial invitee contacts of a conference channel, it is necessary to call <a class="el" href="classTp_1_1ReadyObject.html#ac02393f99a46725a4ffee32caaec13cc">becomeReady()</a> with <a class="el" href="classTp_1_1Channel.html#a05706198daf9f5c92bfca2b29a0744c9">Channel::FeatureConferenceInitialInviteeContacts</a> included in the argument. The required features are documented by each method.</p>
<p>Each channel is owned by a connection. If the <a class="el" href="classTp_1_1Connection.html" title="The Connection class provides an object representing a Telepathy connection.">Connection</a> object becomes dead (as signaled by <a class="el" href="classTp_1_1DBusProxy.html#a2ec4e99262674ba916321d11398c6b58">Connection::invalidated()</a>), the <a class="el" href="classTp_1_1Channel.html" title="The Channel class provides an object representing a Telepathy channel.">Channel</a> object will also get invalidated.</p>

<p><a class="el" href="classTp_1_1Channel.html" title="The Channel class provides an object representing a Telepathy channel.">Channel</a> objects can be created in various ways, but the preferred way is trough <a class="el" href="classTp_1_1Account.html" title="The Account class provides an object representing a Telepathy account.">Account</a> channel creation methods such as <a class="el" href="classTp_1_1Account.html#a67319a5bd8a1d5955176e474ba98d07f">Account::ensureTextChat()</a>, <a class="el" href="classTp_1_1Account.html#a2ba4bbc633f2060ce68d77a599d60e78">Account::createFileTransfer()</a>, which uses the channel dispatcher.</p>
