      ) -> ULTIPA_RESPONSE.ResponseListProperty
      

      Example: Acquire the information of all properties of graphset 'test'

      from ultipa import Connection, UltipaConfig, RequestConfig
      
      # omit code of establishing server connection 'conn' using graphset 'default'
      
      req = conn.showProperty(requestConfig = RequestConfig("test"))
      print(req.toJSON())

      class GetProperty:
      	def __init__(self, type: ULTIPA.DBType, schema: str = None)
      

      Example: Acquire the information of all edge properties of of graphset 'test'

          )
      
      class CommonSchema:
      	def __init__(self, schema: str, property: str)
      

      Example: Craete edge property @transfer.amount for graphset 'test', with data type 'float' and description 'transaction amount'
