<b>Description</b><p>
Your XMPP entity may receive a discovery request for items non-addressable as a JID such as
the MUC rooms where you are joined. In order to answer the correct information it is necessary
to configure the information providers associated to the items/nodes within the Smack client.</p>
<b>Usage</b><p>
In order to configure the associated nodes within the Smack client you will need to create a
NodeInformationProvider and register it with the <i><b>ServiceDiscoveryManager</b></i>. To get
your ServiceDiscoveryManager send <b>getInstanceFor(connection)</b> to the class <i><b>ServiceDiscoveryManager</b></i>
where connection is your XMPPConnection.<br></p>
<p>Once you have your ServiceDiscoveryManager you will be able to register information providers
for the XMPP entity's nodes. To register a new node information provider send <b>setNodeInformationProvider(String node, NodeInformationProvider listener)</b>
to your <i><b>ServiceDiscoveryManager</b></i> where node is the item non-addressable as a JID and
listener is the <i><b>NodeInformationProvider</b></i> to register. To unregister a <i><b>NodeInformationProvider</b></i>
send <b>removeNodeInformationProvider(String node)</b> to your <i><b>ServiceDiscoveryManager</b></i> where
node is the item non-addressable as a JID whose information provider we want to unregister.</p>
<b>Examples</b><p>
In this example we can see how to register a NodeInformationProvider with a ServiceDiscoveryManager that will provide
information concerning a node named "http://jabber.org/protocol/muc#rooms": <br>
<blockquote>
<pre> <font color="#3f7f5f">// Set the NodeInformationProvider that will provide information about the</font>
<font color="#3f7f5f">// joined rooms whenever a disco request is received </font>

<font color="#0000FF">"http://jabber.org/protocol/muc#rooms"</font>,
new NodeInformationProvider() {
public Iterator getNodeItems() {
ArrayList answer = new ArrayList();
Iterator rooms = MultiUserChat.getJoinedRooms(connection);
while (rooms.hasNext()) {
answer.add(new DiscoverItems.Item((String)rooms.next()));
}
return answer.iterator();
}
});
