<h2>QuickStart</h2>
<pre><code>
//create a channel
Channel myChannel = new GroupChannel();
//create my listeners
MyMessageListener msgListener = new MyMessageListener();
MyMemberListener mbrListener = new MyMemberListener();
//attach the listeners to the channel
myChannel.addMembershipListener(mbrListener);
myChannel.addChannelListener(msgListener);
//start the channel
myChannel.start(Channel.DEFAULT);
//create a message to be sent, message must implement java.io.Serializable
//for performance reasons you probably want them to implement java.io.Externalizable
Serializable myMsg = new MyMessage();
//retrieve my current members
Member[] group = myChannel.getMembers();
//send the message
channel.send(group,myMsg,Channel.SEND_OPTIONS_DEFAULT);
</code></pre>
<h2>Interfaces for the Application Developer</h2>
<ol>
<li><code>org.apache.catalina.tribes.Channel</code>
Main component to interact with to send messages
</li>
<li><code>org.apache.catalina.tribes.MembershipListener</code>
Listen to membership changes
</li>
<li><code>org.apache.catalina.tribes.ChannelListener</code>
Listen to data messages
</li>
<li><code>org.apache.catalina.tribes.Member</code>
Identifies a node, implementation specific, default is org.apache.catalina.tribes.membership.MemberImpl
</li>
</ol>
<h3>Interfaces for the Tribes Component Developer</h3>
<ol>
<li><code>org.apache.catalina.tribes.Channel</code>
Main component to that the application interacts with
</li>
<li><code>org.apache.catalina.tribes.ChannelReceiver</code>
IO Component to receive messages over some network transport
</li>
<li><code>org.apache.catalina.tribes.ChannelSender</code>
IO Component to send messages over some network transport
</li>
<li><code>org.apache.catalina.tribes.MembershipService</code>
IO Component that handles membership discovery and
</li>
<li><code>org.apache.catalina.tribes.ChannelInterceptor</code>
interceptors between the Channel and the IO layer
</li>
<li><code>org.apache.catalina.tribes.ChannelMessage</code>
The message that is sent through the interceptor stack down to the IO layer
</li>
<li><code>org.apache.catalina.tribes.Member</code>
Identifies a node, implementation specific to the underlying IO logic
</li>
