Examples How to use this example
ArgumentErrorExample.as
The following example shows how an `ArgumentError` error is generated and handled within a `try..catch` statement. The `println()` function takes one argument, a single string, but because two strings are supplied, the error is thrown. Typically, the compiler might catch such an error, but the `this[]` syntax in the `try` statement bypasses the compiler's syntax checking for the function.
Copy

        import flash.display.Sprite;

        public class ArgumentErrorExample extends Sprite {
            public function ArgumentErrorExample() {
                    println("Hello World");

                    try {
                        this["println"]("Hello", "World");
                    }
                    catch(e:ArgumentError) {
                        trace(e);
                    }
            }

            public function println(str:String):void {
                trace(str);
            }
        }
    }
