Hi,
I started to check if it was possible to have private and protected constructor
in Falcon and I have to admit it was tricky especially because I never seen a
compiler from inside before but it is apparently possible, I've been able to
compile successfully:
package myLib {
public class CTORTest {
private var _p:int;
private function CTORTest(p:int) {
_p = p;
}
private function anotherFct():CTORTest {
return new CTORTest(10);
}
}
}
and using the compiled lib:
<?xml version="1.0"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009";
xmlns:s="library://ns.adobe.com/flex/spark"
creationComplete="creationCompleteHandler(event)">
<fx:Script><![CDATA[
import mx.events.FlexEvent;
import myLib.CTORTest;
private function creationCompleteHandler(event:FlexEvent):void {
var a:CTORTest = new CTORTest(1);
}
]]></fx:Script>
</s:Application>
gives:
[Fault] exception, information=VerifyError: Error #1014: La classe
myLib:CTORTest::CTORTest est introuvable. (not found) with the legacy compiler
and:
F:\sources\falconTestDrive\shell\src\Main.mxml:9
Erreur: Appel d'une méthode qui ne semble pas définie CTORTest. (Call to a
undefined method)
var a:CTORTest = new CTORTest(1);
(I will customize the error message later)
I still need to check it works in the 3 possible ways to instantiate a Class
[1] (at the moment it works only with 1st one), check that works with is /
instanceOf, revisit the cast function accordingly and maybe other things not
yet in my mind and especially check FP won't complain using it.
/* expression = FunctionCallID(KeywordNewID(void), new_type_name,
ContainerID(expression*)) */
/* expression = FunctionCallID(KeywordNewID(void), expression,
ContainerID(expression*)) */
/* expression = FunctionCallID(KeywordNewID(void), vector_literal,
ContainerID(void)) */
In case all this works and I'm far to know it at the moment, I will have to
think about implement "method overloading" otherwise I can't see any usage of a
protected constructor and therefore will probably require some help for the
best way to implement it.
Thanks,
Frédéric THOMAS
