        Args:
            storeFilePrefix(string): the prefix for the JSON file name
            tableName(string): the name of the attribute for which to store the type information
        '''
        JSONAble.storeJsonToFile(self.toJSON(), "%s.json" % storeFilePrefix)
        types=Types.forTable(self, tableName)
        JSONAble.storeJsonToFile(types.toJSON(), "%s-types.json" % storeFilePrefix)
       
 def restoreFromJsonFile(self,storeFilePrefix):
        '''
        restore me from the given storeFilePrefix
        
        Args:
            storeFilePrefix(string): the prefix for the JSON file name
        '''
        jsonStr=JSONAble.readJsonFromFile("%s.json" % storeFilePrefix)
        typesJson=JSONAble.readJsonFromFile("%s-types.json" % storeFilePrefix)
        types=Types(type(self).__name__)
        types.fromJson(typesJson)
        self.fromJson(jsonStr, types)

class Server(JSONAble):
