Hi all,
I am rather new to AspectJ and Equinox Weaving. Despite this I set off to build an Eclipse view that would present the current SWT Controls hierarchy. As the SWT Composite, unlike the AWT Container, does not fire componentAdded events, I came up with an aspect that would intercept all Control creation and let the CompositeListeners be notified about such events.
(CompositeListener is my own interface, as no such thing exists in SWT)
I am using the annotation-based development style, so my aspect that decorates SWT Composite with the CompositeListener support and intercepts Control constructor calls looks like this:
@Aspect
public class CompositeAspect
{
@DeclareParents(value ="org.eclipse.swt.widgets.Composite",
defaultImpl = CompositeExtImpl.class)
ICompositeExt compositeExt;
@AfterReturning(pointcut = "call(org.eclipse.swt.widgets.Control+.new(..))",
returning = "control")
public void afterCallControlConstructor(Control control)
{
Composite parent = c.getParent();
if (parent instanceof ICompositeExt)
{
//aspect was applied, the composite parent has listener support
ICompositeExt compositeExt = (ICompositeExt) parent;
compositeExt.fireControlAdded(control);
}
}
}
This is fine and almost works. When developing this aspect, in the bundle manifest I specified
Eclipse-SupplementBundle: org.eclipse.swt,org.eclipse.jface,org.eclipse.ui,org.eclipse .ui.*
which is enough for enhancing the Composite and catching some of the control creation. However, as controls can be created anywhere by user code, in any bundle, I need to change the directive to
Eclipse-SupplementBundle: *
If I do this, the Eclipse lauch fails with the famous NoSuchMethodError: aspectOf

How can I fix this (apart from adding the missing method by hand, as suggested on http://dev.eclipse.org/mhonarc/lists/aspectj-users/msg11829. html)?
Thank you in advance,
