Re: [flexcoders] Re: Calling static function on Class instance

2008-05-15 Thread Giles Roadnight 
Going back to my project the [functionName] does not work still. the class
reference points to a class that extends a base class. The static function
is in the base class. Is that why it doesn't work?

Thanks

 Thanks Gordon. I got your code to run fine but when I try c.Roadnight()

 I have attached a zip of the project. The compiler error line is commented

 Here is a complete and tested ActionScript app which illustrates four ways
 to call a static function on a Class object. It outputs Roadnight four
 times.



 package

 {



 import flash.display.Sprite;



 public class Giles extends Sprite

 {

 public function Giles()

 {

 super();



 var c:Class = Giles;

 c.Roadnight();

 c[Roadnight]();



 var f:Function;

 f = c.Roadnight;

 f();

 f = c[Roadnight];

 f();

 }



 public static function Roadnight():void

 {

 trace(Roadnight);

 }

 }



 }

 Many thanks for the replies, describeType works great.

 I can't get c.Roadnight to work though and for now am having to create an
 instance of the class to call the function (which I had to make non-static).

 var selectedTemplateClass:Class = initEvent.frameType;
 var xml:XML = selectedTemplateClass.getBlankXML();

 gives a compiler error.

 var selectedTemplateClass:Class = initEvent.frameType;
 var xml:XML = selectedTemplateClass.getBlankXML;

 does not give a compiler error but xml remains null

 I also tried

 var selectedTemplateClass:Class = initEvent.frameType;
 var blankXMLFunction:Function =
 selectedTemplateClass.getBlankXML;
 var xml:XML = blankXMLFunction();

 but blankXMLFunction remains null.

 At the moment I have it working with a fresh instance of the class but I'd
 rather not do it this way if possible.

 Thanks

 Along the same lines - how do I get the class name from a Class object. If
 I do toString() I get [class HeaderImage1]. Do I just have to extract the
 string from that?

 Hi All

 I have a class (BaseTemplate) that is extended to become lots of different
 Template classes.

 I have a list class that takes an array of Class objects to allow a user
 to select a template (the renderer creates an instance of the class).

 When I click an item in the list I want to call a static function on the
 Template.

 When I have a Class object is there anyway of calling a static function on
 that class without creating an instance of the class?

 Thanks

Yes.  Static are not inherited so you have to find the base class that
has the static function.  describeType or getQualifiedSuperClassname()

Create an instance of the class and call getQualifiedClassName() on it.
Or use describeType() on the Class object. The former is probably
faster.
