This section details the usage of Smacks implementation of Entity Capabilities.

<b>XEP related:</b> <a href="http://xmpp.org/extensions/xep-0115.html">XEP-0115: Entity Capabilities</a>

<hr>

<b>Description</b><p>

Entity Capabilities is a XMPP Protocol extension, which, in order to minimize network impact, caches the capabilities of XMPP entities. Those capabilities are determined with the help of the Service Discovery Protocol (<a href="http://xmpp.org/extensions/xep-0030.html">XEP-0030</a>).

</p>

<b>Usage</b><p>

Entity Capabilities work silenty in background when enabled. If the remote XMPP entity does not support XEP-0115 but XEP-0030 then XEP-0030 mechanisms are transparently used. You can enable or disable Entity Capabilities by using <i><b>EntityCapsManager</b></i>.<br>

The cache used by Smack for Entity Capabilities is non-persistent as default. That is, the cache only uses memory. But it is also possible to set a persistent Entity Capabilities cache, which is recommended.
</p>

<b>Examples</b><p>

Enable Entity Capabilities
<br>
<blockquote>
<pre>
      <font color="#3f7f5f">// Get an instance of entity caps manager for the specified connection</font>
      Entity CapabilitiesManager mgr = new EntityCapsManager.getInstanceFor(con);

      <font color="#3f7f5f">// Enable entity capabilities</font>
      mgr.enableEntityCaps();
</pre>
</blockquote>

Configure a persistent cache for Entity Capabilities
<br>
<blockquote>
<pre>
      <font color="#3f7f5f">// Get an instance of entity caps manager for the specified connection</font>
      Entity CapabilitiesManager mgr = new EntityCapsManager.getInstanceFor(con);

      <font color="#3f7f5f">// Create an cache, see smackx.entitycaps.cache for pre-defined cache implementations</font>
      EntityCapsPersistentCache cache = new SimpleDirectoryPersistentCache(new File("/foo/cachedir"));

      <font color="#3f7f5f">// Set the cache</font>
      mgr.setPersistentCache(cache);
</pre>

SMACK-431 Entity Capabilities are now enabled as default for new connections. Added an extensions documentation html page. git-svn-id: http://svn.igniterealtime.org/svn/repos/smack/trunk@13686 b35dd754-fafc-0310-a699-88a17e54d16e 2013-06-22 19:00:40 +02:00			`<html>`
