Example 2 with AnnotationProxyClass

use of org.eclipse.ceylon.model.loader.model.AnnotationProxyClass in project ceylon by eclipse.

the class AbstractModelLoader method makeInteropAnnotation.

/**

 * For a Java declaration {@code @interface Annotation} we generate
 * a model corresponding to:

 *   annotation JavaAnnotation javaAnnotation(...) => JavaAnnotation$Proxy(...);
 * </pre>
 *
 * We also make a {@code *__method}, {@code *__field} etc version for each
 * {@code @Target} program element
 * @param iface The model of the annotation @interface
 * @param container The container in which the generated members belong
 * @return A list of members to add to the container
