The experimental hasmethod() pointcut matches methods that are declared in superclasses.

Having a hasDeclaredMethod() pointcut would allow to provide different implementation for a method without risking conflicts with Inter Type Declarations.

Example:

aspect myITD {
  public void MyHelloInterface.sayHello() {
    System.out.println("hello");
  }

  declare parents: !hasDeclaredMethod(void *.sayHello()) implements MyHelloInterface;
}

This way the ITD would never clash with classes that already have a sayHello().

Sometimes we could achieve this result, by injecting the ITD into the superclass of the class we want to advise, but that is not always possible.
