Re: [aspectj-users] Adding getter/setter using AspectJ

[Andy Clement <andrew.clement@xxxxxxxxx>]

Hi Setya,

Well, you can write ITDs but those ITDs aren't parameterizable.

class DomainClass {
  int someProperty;
}

aspect Injector {
  public int DomainClass.getSomeProperty() {
    return someProperty;
  }
  public void DomainClass.setSomeProperty(int someProperty) {
    this.someProperty = someProperty;
  }
}

You can't write a more general definition that says 'for a field that
looks like that, create a method that looks like this'.

Spring Roo uses the ITD mechanism above, it generates the aspects for
many kinds of thing (getters/setters/toString/hashcode/equals/etc) and
then looks after keeping them up to date for you, you don't have to
maintain them yourself, you just work on the domain classes.

It wouldn't be all that difficult to extend AspectJ and define an
annotation that then triggered AspectJ to create accessors
(getters/setters) for any field that has that annotation, I just
haven't had that many users express an interest in AspectJ supporting
it.

cheers
Andy
