> Change new Java API functions to SAMs
> -------------------------------------
>
> Key: FLINK-701
> URL: https://issues.apache.org/jira/browse/FLINK-701
> Project: Flink
> Issue Type: Improvement
> Components: Java API
> Reporter: GitHub Import
> Assignee: Kostas Tzoumas
> Labels: github-import
> Fix For: pre-apache
>
>
> In order to support a compact syntax with Java 8 Lambdas, we would need to
> change the types of the functions to Single Abstract Method types (SAMs).
> Only those can be implemented by Lambdas.
> That means that DataSet.map(MapFunction) would accept an interface
> MapFunction, not the abstract class that we use now. Many UDFs would not
> inherit form `AbstractFunction` any more. The inheritance from
> AbstractFunction would be optional, if life cycle methods (open / close) and
> runtime contexts are needed.
> This may have also implications on the type extraction, as the generic
> parameters are in generic superinterfaces, rather than in generic
> superclasses.
