Subject [jira] [Created] (FLINK-2637) Add abstract equals, hashCode and toString methods to TypeInformation
Date Tue, 08 Sep 2015 15:11:47 GMT
Fabian Hueske created FLINK-2637:
------------------------------------

             Summary: Add abstract equals, hashCode and toString methods to TypeInformation
                 Key: FLINK-2637
                 URL: https://issues.apache.org/jira/browse/FLINK-2637
             Project: Flink
          Issue Type: Improvement
          Components: Core
    Affects Versions: 0.9, 0.10
            Reporter: Fabian Hueske
             Fix For: 0.10


Flink expects that implementations of {{TypeInformation}} have valid implementations of {{hashCode}}
and {{equals}}. However, the API does not enforce to implement these methods. Hence, this
is a common origin for bugs such as for example FLINK-2633.

This can be avoided by adding abstract {{hashCode}} and {{equals}} methods to TypeInformation.
An abstract {{toString}} method could also be added.

This change will brake the API and require to fix a couple of broken {{TypeInformation}} implementations.
