[jboss-dev-forums] [Design the new POJO MicroContainer] - Re: StructureContext and candidate annotations

[alesj]

I've added this to AbstractStructureDeployer:

  |    /**
  |     * Create deployment resource loader.
  |     *
  |     * @param root the deployment root
  |     * @return new deployment resource loader
  |     */
  |    protected abstract DeploymentResourceLoader createDeploymentResourceLoader(VirtualFile root);
  | 
  |    /**
  |     * Create annotation environment.
  |     *
  |     * @param classLoader the classloader
  |     * @return new annotation environment
  |     */
  |    protected abstract AnnotationEnvironment createAnnotationEnvironment(ClassLoader classLoader);
  | 
  |    /**
  |     * Check for candidate annotations.
  |     * 
  |     * @param context the structure context
  |     * @param roots the roots to check
  |     */
  |    protected void checkCandidateAnnotations(StructureContext context, VirtualFile... roots)
  |    {
  |       if (roots == null || roots.length == 0)
  |          throw new IllegalArgumentException("Null or empty roots");
  | 
  |       if (candidateAnnotations == null || candidateAnnotations.isEmpty())
  |          return;
  | 
  |       for(VirtualFile root : roots)
  |       {
  |          DeploymentResourceLoader loader = createDeploymentResourceLoader(root);
  |          ClassLoader cl = new DeploymentResourceClassLoader(loader);
  |          AnnotationEnvironment env = createAnnotationEnvironment(cl);
  |          for (Class<? extends Annotation> annotationClass : candidateAnnotations)
  |          {
  |             if (env.hasClassAnnotatedWith(annotationClass))
  |             {
  |                context.addFoundAnnotation(annotationClass);  
  |             }
  |          }
  |       }
  |    }
  | 
Where MockEARStructureDepolyer then checks in
Module's StructureContext if we have any matching annotation.

OK?
