Re: [aspectj-users] Need to enumerate all methods for selected advices o

["Wes Isberg" <wes@xxxxxxxxxxxxxx>]

Hi -

-messageHolder is not in 1.5.0, but should be in the latest dev build
on the downloads page:

  http://www.eclipse.org/aspectj/downloads.php
  http://www.eclipse.org/downloads/download.php?file=/technology/aspectj/dev/aspectj-DEVELOPMENT-20060303105327.jar

(But I can't say I've tested it myself.)

Even in 1.5.0 you can programmatically invoke ajc.Main.  The example at
the bottom of the ajc section of the devguide shows how to specify a
message handler/holder - I've copied it below.

btw, another option is to use the -crossrefs option to generate a .ajsym file
and then interpret that.

import org.aspectj.bridge.*;
import org.aspectj.tools.ajc.Main;
import java.util.Arrays;

public class WrapAjc {
  public static void main(String[] args) {
    Main compiler = new Main();
    MessageHandler m = new MessageHandler();
    compiler.run(args, m);
    IMessage[] ms = m.getMessages(null, true);
    System.out.println("messages: " + Arrays.asList(ms));
  }
}
