Question on variable, method, access scope

im still new to actionscript, but i do have OOP background.
it goes like this

//
//Connection.as
//
class Connection
{
var host:String;
var port:Number;
var dhandler_xmlsocket:XMLSocket;

function Connection(my_host, my_port)
{
this.host = my_host;
this.port = my_port;
this.dhander_xmlsocket = new XMLSocket();
this.dhander_xmlsocket.onConnect = function(success)
{
////////////////////////////////////////////////////////////
// how to access do_something_exciting() from here
// or other Connection’s variables and methods?
////////////////////////////////////////////////////////////
}
} // end of constructor

function do_something_exciting()
{
//do something really exciting;
}

} // end of class Connection
