[ews.eclipse.technology.aspectj] Inherited annotations, interfaces and e

[Mario Scalas <mario.scalas@xxxxxxxxx>]

I read in [1] that I could capture join points by using inherited
annotations. The example shown there uses class inheritance (and call()
join point) but I thought that the same idea could work for implementing
interfaces and with execution(). Though, it doesn't work and so before
surrendering I want to ask to the ng.

[My annotation]

@Target( ElementType.METHOD )
@Inherited
@Retention( RetentionPolicy.RUNTIME )
public @interface MyAnnot {
    String value() default "";
}

[Annotated interface]

public interface IMain {
    @MyAnnot( value = "bla" )
    void doSomething();
}

[Implementation (the implemented methods should inherit the annotation)]

public class Main implements IMain {
    public static void main( String[] args ) {
        IMain m = new Main();
        
        m.doSomething(); // If I use the "call()" pointcut I capture this
    }

    public void doSomething() {
        int c = 3 + 2;
        System.out.println( "c = " + c );
    }
}

[The aspect]

@Aspect
public class MyAspect {
    // If I use call() instead of execution() it works fine
    @Pointcut( "execution( @MyAnnot * *.*(..) ) && @annotation( a )" )
    protected void annotatedMethods( MyAnnot a ) {}

    @Around( "annotatedMethods( a )" )
    public void checkAnnotations( ProceedingJoinPoint jp, MyAnnot a ) 
            throws Throwable {
        if ("bla".equals( a.value() ))
            System.out.println( "Bla!" );
        jp.proceed();
    }
}

So, am I triying to do something really stupid? Or I'm just implementing my
idea in the wrong way?

Thanks!
Mario
