This section details the usage of Smacks implementation of Entity Capabilities.
</p>
<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 an extension to the Service Discovery (<a href="http://xmpp.org/extensions/xep-0030.html">XEP-0030</a>), which, in order to minimize network impact, caches the capabilities information of XMPP entities.
</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>
</blockquote>
