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.

package {
    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);
        }
    }
}
