RE: [aspectj-users] toString Aspect aspect browser

[jon.pallas@xxxxxxxxxxx]

Thanks Ron

I now see that i should have used execution() rather than call()


The problem is that if

public String toString()  if is implemented only in java.lang,Object;

The aspect cant find it as a joinpoint.

if i implement toString() in my class

public String toString() { return "You wont see this because the aspect 
will get there first";}

It is found by the asect and i get my nice string out.


Is there a way around this??

Thanks again 
Jon

Jon,

I got it to work with the following:

       public pointcut myClass(Object obj) : within(com.philips.sct..*)
                                 && this(obj);

                 public pointcut myToString(Object obj) : 
                                 myClass(obj)
                                 && execution(public String toString());

                 String around(Object obj) : myToString(obj) {
                                 return StringUtil.toString(obj); 
                 }

Thanks,

Ron DiFrango

Hi All 


I am new to aspectj so I may be doing something simple wrong any help 
would be apperciated.

I have writen an Aspect that i want to intersept any call to toString(). 
The code is below
using the aspect browser in eclipse i can see that it only affects classes 

that are not in 
com.philips.sct? but his is what i want tbe be affected? 

Is it just the browser or is it my code?

Thanks
Jon

package com.philips.sct.aspects;

import com.philips.common.util.StringUtil;

public aspect ToStringEnhancerAspect {
 
        public pointcut myClass(Object obj) : within(com.philips.sct..*) 
&& this(obj);

 
        public pointcut myAspects() : within(com.philips.sct.aspects.*);
 
 
        public pointcut myToString(Object obj) : !myAspects()
                        &&  myClass(obj)
                        &&  call(public String toString())
                        ;

        String around (Object obj): myToString(obj){
                return StringUtil.toString(obj); 
        }
