Is there a way to extend the String class that is more straightforward
to use (or otherwise better) than this:
StringExtra.as:
dynamic class com.mydomain.core.StringExtra extends String {
function StringExtra (input) {
super(input);
}
public function replace(sFind:String, sReplace:String):String {
return this.split(sFind).join(sReplace);
}
}
in fla:
import com.mydomain.core.StringExtra;
var x:StringExtra = new StringExtra("This is my address");
_txt.text = x.replace('address', 'phone');
so that, for example, I could use the replace method on a String object
instead of having to declare an object of type StringExtra to do this?
It was so straightforward to do with String.prototype in Flash MX -- I
seem to have made this too complicated, but I can't find another way to
get it to work with as2 classes. Does anyone have a library or some
examples of extensions of core classes like String, Math, Date...?
tia (floundering around in as2-land),
Helen
