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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
