Re: [aspectj-users] Addressing classes that arent being compiled

[Mark Kattenbelt <kattenbe@xxxxxxxxxxxxx>]

Hello,

Thank you for your reply. I had tried this, however without the '+', as 
this is new to me (as I understand this means also for any subclass). It 
matches fine when I use:

pointcut textFieldInit () :
       call(JTextField+.new(..));
      
after () returning : textFieldInit()
{
       System.out.println("TextFieldInit!");   
}   

This matches fine, but I cannot relate to the instance of JTextField. 
Due to the nature of my experimenting I would like to get hold of the 
actual instance of the JTextField after it has been initialised, so I 
figured to use the following:

pointcut textFieldInit (JTextField textField) :
       call(JTextField+.new(..)) && target(textField);
      
after (JTextField textField) returning : textFieldInit(textField)
{
       System.out.println("TextFieldInit!" + textField);    
}

Now this does not match very well as I receive the following error:

D:\..\userinterface\TestAspect.aj:22 [warning] advice defined in 
userinterface.TestAspect has not been applied [Xlint:adviceDidNotMatch]
after (JTextField textField) returning : textFieldInit(textField)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

So something is going wrong there :-(, what am I doing wrong? Or am I 
trying to do something that isn't that natural? (I am making new 
instances of JTextField obviously in my program...)

Cheers,

Mark
