<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);
