exporter("deleteMetadata", deleteMetadata);
    function DecorateConstructor(decorators, target) {
        for (var i = decorators.length - 1; i >= 0; --i) {
            var decorator = decorators[i];
            var decorated = decorator(target);
            if (!IsUndefined(decorated) && !IsNull(decorated)) {
                if (!IsConstructor(decorated))
                    throw new TypeError();
                target = decorated;
            }
        }
        return target;
    }
