Greg Hogan created FLINK-3877:
---------------------------------
Summary: 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.
