Hi,
I cannot reach some of the fields of my class and I don't understand why.
Someone please take a look at my code. This is the Nth one, I was changing
this to var, to TCPServer.prototype.sg etc. Nothing helped.
I've started with a sample tcp server from Anwajler's blog
here<http://anwajler.com/node.html>.
It was working well, but I would like to put it into a seperate file, into
a module. I've created my TCPServer class as follows:
var net = require('net');
var GatewayClass = require('./Gateway.js');
exports.TCPServer = TCPServer;
function TCPServer(host, port) {
this.HOST = host;
this.PORT = port;
var tcpServer = net.createServer();
this.gatewayList = [];
this.findByAddressAndPort = function (address, port) {
var i;
for(i = 0; i < gatewayList.length; i++){
if(gatewayList[i] !== undefined) {
if(gatewayList[i].IP === address && gatewayList[i].Port === port) {
return gatewayList[i];
}
}
}
};
this.dataHandler = function (stream, data) {
var gateway = this.findByAddressAndPort(stream.remoteAddress,
stream.remotePort);
gateway.Buffer.Add(data);
};
this.onData = function(data) {
this.dataHandler(this, data);
}
this.onClose = function(){
console.log('CONNECTION CLOSED');
};
this.onError = function(exception) {
console.log('SOCKET ERROR: ' + exception);
};
this.onListen = function() {
tcpServer.on('connection', this.onConnection);
tcpServer.on('error', this.onError);
tcpServer.on('close', this.onClose);
console.log('Server listening on ' + this.HOST +':'+ this.PORT);
};
this.onConnection = function (stream) {
var gw=new GatewayClass.Gateway(stream);
gatewayList.push(gw);
stream.on('data', onData);
console.log("Clients: ", gatewayList.length);
};
this.Open = function() {
tcpServer.listen(this.PORT, this.HOST, this.onListen);
}
}
TCPServer.prototype.Listen = function() {
this.Open();
}
In my main application I create an instance of TCPServer and start
listening this way:
var TCPServerClass = require('./tcpserver.js');
var TCPServer = new TCPServerClass.TCPServer(GLOBALS.HOST, GLOBALS.PORT);
TCPServer.Listen();
Thanks for your help. This version says:
events.js:130
throw TypeError('listener must be a function');
^
TypeError: listener must be a function
at TypeError (<anonymous>)
at Server.EventEmitter.addListener (events.js:130:11)
