In traditional AspectJ I would do something like below. I didn't get one
working, but it was something like this.
after(String s) : call(javax.swing.JTextField.new(s)) && args(s) &&
if(s.equals("textField1") //find out where the JTextfield with text
"textField1" is instantiated, and run the code below
{
//code here (is there a technical term to call the code block in here?)
undoService.addCallback(new ActionListener()
{
public void actionPerformed(ActionEvent ae)
{
undoService.addEdit(new UndoableEditDocumentCustom(textField));
}
});
}
The point is to find the JTextField with a starting text of "textField1", which
is not a good way to identify the JTextField I want, but this is just for proof
of concept purposes. Once the correct JTextField is found, execute the code.
With annotations, would it be simple to add this code for a specific
JComponent? Can the annotation go right on top of the JComponent instantiation
code? Can the annotation do some extra processing to know if the JComponent is
a JTextField or JButton so I can call specific code for both? Sorry if I am not
perfectly clear, I am still really green.

Can you show what you intent to do with the traditional syntax? That will help
in showing if and how it can be mapped to @AspectJ.

Hey all,
I have AspectJ working real nice right now and I would like to see if @AspectJ
can let me do those same things in a slicker fashion. I can illustrate want I
am thinking about by showing my function:
undoService.addCallback(new ActionListener()
{
public void actionPerformed(ActionEvent ae)
{
undoService.addEdit(new UndoableEditDocumentCustom(textField));
}
});
Right now my actionPerformed is hard-wired to send my undoService that
particular UndoableEdit for a JTextfield. I'd like to automate the process of
adding these edits. Could I possibly add an annotation above my JComponents
that would be able to call the code above based on the type of JComponent it
is? I think I know how to do this in AspectJ, but I am having a hard time
grasping how @AspectJ works, so any suggestions or pointers would be great :)
