is a code example for changing our presence to let people know we're unavailable
because we're "out fishing":<p>
<div class="code">
<pre>
<font color="gray"><i>// Create a new presence. Pass in false to indicate we're unavailable.</i></font>
Presence presence = new Presence(false);
Presence presence = new Presence(Presence.Type.UNAVAILABLE);
presence.setStatus(<font color="green">"Gone fishing"</font>);

Every connection has a <tt>PacketReader</tt> and <tt>PacketWriter</tt>. The
packet reader listens for XML data from the server and parses it into
individual packets. You can listen for incoming packets by registering
<tt>PacketWatcher</tt> objects with the packet reader. The packet writer
is responsible for writing packets to the server. It takes <tt>Packet</tt>
objects and converts them to XML before sending them over the network.
Smack provides two ways to read incoming packets: <tt>PacketListener</tt>, and
<tt>PacketCollector</tt>. Both use <tt>PacketFilter</tt> instances to determine
which packets should be processed. A packet listener is used for event style programming,
while a packet collector has a result queue of packets that you can do
polling and blocking operations on. So, a packet listener is useful when
you want to take some action whenever a packet happens to come in, while a
packet collector is useful when you want to wait for a specific packet
to come through. Packet collectors and listeners can be created using the
connection object.
