HiveMind 2.0: Interceptors

[James Carman <ja...@carmanconsulting.com>]

All,

I would also like to come up with a way to allow interceptors to be added to
service points based upon some criteria.  Maybe we could have
InterceptorInjector or something.  I don't know.  But, in Spring, I can use
annotations (@Transactional for instance) to decide whether an interceptor
needs to be added to a "bean."  I'd like to be able to do the same thing
with HiveMind.  Thoughts/ideas?

James

I'd prefer the plain java way for such things.
The refactoring I mentioned here 
(http://article.gmane.org/gmane.comp.jakarta.hivemind.devel/2333)
allows such things quite easily:

You can register a new RegistryProvider, that is called by the 
RegistryBuilder during registry construction:

class MyRegistryProvider {
  public void postProcess(RegistryConstruction construction) {
     // get all service points registered by all modules
     List servicePoints = construction.getServicePointDefinitions();
     for (.....) {
          if (whateverIsTrue)
             construction.addIntercepter(currentServicePointDef, 
myInterceptor);
     }
  }
}

Or what about an interceptor factory in a annotated module that gets all 
service implementations
when they are constructed, so it could decide what to do?

public class MyModule()
{
    @interceptorFactory(id='myInterceptor')
    public void addMyInterceptor(Object coreImplementation) {
       if (coreImplementation.getClass().hasAnnotation("transactional")) {
            addInterceptor(coreImpolementation, myInterceptor);
       }
    }
}
