#Usage example
##Server
Configuration config = new Configuration();
config.setHostname("localhost");
config.setPort(81);
config.setListener(handler);
SocketIOServer server = new SocketIOServer(config);
server.addMessageListener(new DataListener<String>() {
@Override
public void onData(SocketIOClient client, String message) {
...
}
});
String eventName = ...
server.addEventListener(eventName, new DataListener<Object>() {
@Override
public void onData(SocketIOClient client, Object data) {
...
}
});
server.addConnectListener(new ConnectListener() {
@Override
public void onConnect(SocketIOClient client) {
...
}
});
server.addDisconnectListener(new DisconnectListener() {
@Override
public void onDisconnect(SocketIOClient client) {
...
}
});
server.addJsonObjectListener(new DataListener<Object>() {
@Override
public void onData(SocketIOClient client, Object data) {
...
// send object to socket.io client
SampleObject obj = new SampleObject();
client.sendJsonObject(obj);
}
});
server.start();
...
server.stop();

// here is your handler on messages from server
});

// connection established, now we can send an objects
// send json-object to server
