             Project: Flink
          Issue Type: New Feature

            Reporter: Greg Hogan

            Priority: Minor
             Fix For: 1.2.0


Existing translators convert from LongValue (the output label type of graph generators) to IntValue, StringValue, and an offset LongValue. Translators can also be used to convert vertex or edge values. This translator will be appropriate for translating these vertex or edge values to NullValue when the values are not used in an algorithm.
