> Create TranslateFunction interface for Graph translators
> --------------------------------------------------------
>
> Key: FLINK-3877
> URL: https://issues.apache.org/jira/browse/FLINK-3877
> Project: Flink
> Issue Type: Bug
> Components: Gelly
> Affects Versions: 1.1.0
> Reporter: Greg Hogan
> Assignee: Greg Hogan
> Priority: Minor
> Fix For: 1.1.0
>
>
> I now recall why FLINK-3771 had a {{Translator}} interface with a
> {{translate}} method taking a field for reuse: when we translate edge ID the
> translator must be called twice.
> {{TranslateFunction}} will be modeled after {{MapFunction}} and
> {{RichTranslateFunction}} will be modeled after {{RichMapFunction}}.
> The unit test should have caught this but I was reusing values between fields
> which did not detect that values were overwritten.
