> Key: NIFI-1826
> URL: https://issues.apache.org/jira/browse/NIFI-1826
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Affects Versions: 0.6.1
> Reporter: Pierre Villard
> Assignee: Pierre Villard
> Priority: Minor
>
> It would be useful to add a function returning true if a string is in a list
> of arguments and false otherwise.
> Example:
> {noformat}
> if ${myEnum} = "JOHN"
> then
> ${myEnum:in("PAUL", "JOHN", "MIKE")} returns true
> and
> ${myEnum:in("RED", "GREEN", "BLUE")} returns false
> {noformat}
> This would be particularly useful in RouteAttribute processor to perform
> conformity verifications on flow files.
