Tuple

If you are writing data to a stream, you create a tuple object, fill it with data, then write it to the stream. Similarly, if you are reading data from a stream, you receive a row of data, read the individual values from the tuple object, and then write the data to your chosen destination.

• getcolumnnames() – Returns a list that contains the names of the tuple columns.
• gettimestamp() – Gets the tuple's timestamp, expressed as the number of seconds (not microseconds) since midnight January 1, 1970.

  The time module in the Python library contains functions to convert between seconds and more human-readable formats such as "YYYY-MM-DD HH24:MI:SS".

• getvalue(self, name) – Gets the value in the field specified by the name parameter.
• setvalue(self, name, value) – Sets the value in the field specified by the name parameter to the value specified in the value parameter.
• getvalues(self) – Gets the value in the field specified by the name parameter.
• setvalues(self, value) – Sets the value in the field specified by the name parameter to the value specified in the value parameter.
• getcsv(self) – Returns the tuple as a single CSV string.The first field in the CSV string is the row timestamp value in microseconds since 00:00:00 Jan 1, 1970.
• setcsv(self, str) – Given a string that contains comma-separated values, set the values of the fields in the tuple to the values in the string. Note that the first field in the CSV string should be the row timestamp value in microseconds since 00:00:00 Jan 1, 1970.
