Examples of org.apache.xbean.asm5.ClassReader.accept()

org.apache.xbean.asm5.ClassReader.accept()
Makes the given visitor visit the Java class of this {@link ClassReader}. This class is the one specified in the constructor (see {@link #ClassReader(byte[]) ClassReader}). @param classVisitor the visitor that must visit this class.

        Class clazz = classToProxy;
        while (clazz != null && !clazz.equals(Object.class)) {
            try {
                final ClassReader classReader = new ClassReader(readClassFile(clazz));
                final ClassVisitor copyMethodAnnotations = new CopyMethodAnnotations(visitors);
                classReader.accept(copyMethodAnnotations, ClassReader.SKIP_CODE);
            } catch (final IOException e) {
                throw new ProxyGenerationException(e);
            }
            clazz = clazz.getSuperclass();
