> Pattern(Flat)SelectFunctions should support RichFunction interface
> ------------------------------------------------------------------

> Key: FLINK-8159
> URL: https://issues.apache.org/jira/browse/FLINK-8159
> Project: Flink
> Issue Type: Sub-task
> Components: CEP
> Reporter: Dian Fu
> Assignee: Dian Fu
> Priority: Major
>
> {{SelectWrapper}} and {{FlatSelectWrapper}} should extends
> {{AbstractRichFucntion}} and process properly if the underlying functions
> extend RichFunction.
> Things to be very careful about:
> * backwards compatibility (we previously serialized conditions) - changes to
> those interfaces have to be done carefully
> * we want to be able to add dynamic patterns in the future, so at some point
> we have to open also on control message arrival
