Jochen Theodorou commented on GROOVY-8573:
------------------------------------------
To have a realistic version you need to say something about iterator. The best
way to do this is by implementing Iterable. And for this case we have an
each-method and an eachWithIndex variant as well. In my opinion we should close
this issue and GROOVY-8574
> Add @ClosureParams to each/eachWithIndex methods in DefaultGroovyMethods

> Key: GROOVY-8573
> URL: https://issues.apache.org/jira/browse/GROOVY-8573
> Project: Groovy
> Issue Type: Improvement
> Affects Versions: 2.6.0-alpha-3, 3.0.0-alpha-2, 2.4.15, 2.5.0-rc-2
> Reporter: Eric Milles
> Priority: Minor
>
> Category methods {{each(T,Closure)}} and {{eachWithIndex(T,Closure)}} are
> missing {{@ClosureParams}} annotations.
> From some cursory testing, it looks like these are the necessary additions:
> {code:java}
> public static <T> T each(T self, @ClosureParams(value=FromString.class,
> options={"T"}) Closure closure)
> public static <T> T eachWithIndex(T self,
> @ClosureParams(value=FromString.class, options="T,Integer") Closure closure)
> {code}
