[osflash] Aspect Oriented Programming

[lieven.cardoen@pointx.be]

Hi Simon, I'm trying to figure out this part of As2lib. It looks great,
but I don't have the time to look how it exactly works. This is what I
have so far : 

 

private static function
initLogMethodExecutionsAspect(weaver:SimpleWeaver):Void {

                                    var
logMethodExecutionsAspect:LogMethodExecutionsAspect = new
LogMethodExecutionsAspect();

 
//weaver.addAspect(logMethodExecutionsAspect,
_global.be.idiomatic.framework.content);

 
weaver.addAspect(logMethodExecutionsAspect,
_global.be.idiomatic.module);

 
weaver.addAspect(logMethodExecutionsAspect, _global.org.as2lib.env.log);

                        }

            

            

            

 
//==================================================================

            //          PUBLIC METHODS

 
//==================================================================

                        public static function
init(target:MovieClip):Void{

                                    // use two separated try-catch
blocks because the application may run even if the weaving process
failed

                                    try {

                                                var weaver:SimpleWeaver
= new SimpleWeaver();

 
initLogMethodExecutionsAspect(weaver);

                                                weaver.weave();

                                    } catch
(exception:org.as2lib.env.except.Throwable) {

                                                // send email to
application programmer

                                                if
(logger.isErrorEnabled()) {

 
logger.error("Weaving failed with exception:\n" +
StringUtil.addSpaceIndent(exception.toString(), 2));

                                                }

                                    }

                                    

                                    target.attachMovie("Application",
"application", 1);

                        }

 

 

My question is how does the  LogMethodExecutionsAspect class look like.
I haven't begun programming this class. All it should do is send a
message at the beginning of a method and at the end saying which class
and method the program is in. Do you have an example of such an Aspect?

 

Thx, greetz
