Well I would prefer default arguments instead.
function split(s:String, delim:String):Array
{
if (delim == undefined)
delim = ; // default to space character
...
}
So you can pass one or two arguments to the split function. That's
method overloading. You can also type one of your arguments as Object
and then check the type inside the function using the instanceof
operator. That's more method overloading. :) But no true method
overloading as in Java or C++.

[flexcoders] How to overload methods in Actionscript?
When I use same method name more than once (with additional arguments), Flex compiler says I can't use the same name more than once. Is this really true (Flex doesn't support method overloading?) or do I need to do something different? Thanks, Libby Yahoo! Groups Sponsor ~-- Most low income households are not online.

RE: [flexcoders] How to overload methods in Actionscript?
Hi,
ActionScript doesn't support method overloading. Instead you can use
following approach.
function sayHello()
{
var n:Number = arguments.length;
if(n==0)
{
alert(Hello World);
}
else if(n==1)
{
alert(Hello + arguments[0]);
}
else if(n==2)
{
alert(Hello + arguments[0] + + arguments[1]);
}
}
//usage:
sayHello();
sayHello(Abdul);
sayHello(Abdul, Qabiz);
You can access individual argument using arguments array. You can use
typeof and instanceof to find the type of each argument and have a
switch logic to perform different algorithm for different set of
arguments.
Does that make sense?
