Unfortunately the source code line is not captured in the joinpoint object, nor is the entire source encoded in the class file so that the relevant snippet could be extracted at runtime. You'd have to read the relevant source file and pull out the text you need.

cheers,

Andy

Hi,

Is there a way in aspect to read the source line as it is.

Say for example. My Java class code

public static void main(String[] args)throws IOException,SQLException

{
   Vector testvector = new Vector();
     testvector.add("abc");
}

I want to read the source line Vector testvector= new Vector();

When i use
SourceLocation sl =thisJoinPointStaticPart
.getSourceLocation();

Which is giving me the file details and line number details but not the source line read ..

Thanks,

Hi Users,

Go through the following steps once.

1) My Java class code

public static void main(String[] args)throws IOException,SQLException

{
   Vector testvector = new Vector();
     testvector.add("abc");
   }

2) Aspect Implementation

pointcut allConstructors() : call( * java.util..add(..));

Object around() : allConstructors() {
Object[] objarr = thisJoinPoint.getArgs();

for (int i = 0; i < objarr.length; i++)

{
  System.out.println("object is..."+objarr[i]);//This will give me tha value "abc"
}

Similarly if i want to get the object testvector and i want to perform the testvector.size() operation on it.
How to capture this testvector object, if i use this or getTarget() which is returning null.

Please suggest the way to make it possible.

Thanks,
Krishnachaitanya Jasty
