else:
    string_types = basestring


class JsonDumper(object):
    def __init__(self, **kwargs):
        self.kwargs = kwargs

    def __call__(self, obj, dest=None):
        if dest is None:
            return json.dumps(obj, **self.kwargs)
        else:
            return json.dump(obj, dest, **self.kwargs)


default_dumper = JsonDumper()


class JsonLoader(object):
    def __init__(self, **kwargs):
        self.kwargs = kwargs

    def __call__(self, src):
        if isinstance(src, string_types):
            return json.loads(src, **self.kwargs)
        else:
            return json.load(src, **self.kwargs)
