def __init__(self, **args):
            # Just a hack to prevent any exceptions
            Having.__init__(self, type="equalTo", aggregation=None, value=None)

            self.having = {
                "having": {
                    "type": "dimSelector",
                    "dimension": args["dimension"],
                    "value": args["value"],
                }

def __init__(self, **args):
        # Just a hack to prevent any exceptions
        Having.__init__(self, type='equalTo', aggregation=None, value=None)
