[aspectj-users] Equinox Aspects LTW: capturing aspect instantiation

[Mario Scalas <mario.scalas@xxxxxxxxx>]

Hi all!

   Does Equinox Aspects supports pointcuts defined on other aspects defined in the aop.xml file? That is, I have in my bundle:

<?xml version="1.0" encoding="UTF-8"?>

<aspectj>

    <aspects>

    <!-- SWT Thread Safety -->

   <concrete-aspect name="it.uniba.di.cdg.jtalk.aspects.SWThreadingAspect" 

     extends="it.uniba.di.cdg.penelope.ui.swt.AbstractSWThreadingAspect">

     <pointcut name="scope" _expression_="within( it.uniba.di.cdg.jtalk.ui..* )"/>

   </concrete-aspect>

             <!-- Aspect Injector -->

             <concrete-aspect name="it.uniba.di.cdg.jtalk.aspects.AspectInjectionAspect" 

     extends="it.uniba.di.cdg.penelope.AbstractAspectInjectionAspect">

     <pointcut name="scope" _expression_="within( it.uniba.di.cdg.jtalk.aspects.SWThreadingAspect )"/>

   </concrete-aspect>

    </aspects>

</aspectj>

I want AspectInjectionAspect to capture the instantiation of the SWThreadingAspect:

@Aspect // Work in progress!

public abstract class AbstractAspectInjectionAspect {

@Pointcut( "" )

protected abstract void scope();

@Pointcut( "scope() && execution( public it.uniba.di.cdg.penelope.IConfigurableAspect+.new() ) && this( aspectInstance )" )

protected void aspectInstantiation( Object aspectInstance ) { }

@After( "aspectInstantiation( aspectInstance )" )

public final void afterActivation( Object aspectInstance ) {

System.out.println( "WOW! Instantiated aspect: " + aspectInstance );

}

}

The target aspect is defined as (IConfigurableAspect is just a marker interface with no method):

@Aspect

public abstract class AbstractSWThreadingAspect implements IConfigurableAspect {

// ... other stuff 

@Pointcut( "" )

public abstract void scope();

public AbstractSWThreadingAspect() {

super();

System.out.println( "AbstractSWThreadingAspect()" );

}

// ...  other stuff

}

My RCP application works ok (the SWT Aspect is correctly woven at load time but I see that the instantiation is not captured by my injector aspect. Is this a completely doomed-to-failure approach? (Using AJDT 2.0.1 and eclipse 3.5.1 here)

Thanks

Mario
