Eric Milles commented on GROOVY-11168:
--------------------------------------
So for "Foo foo = Stub \{ ... }" there are 2 possibilities for the IDE:
# The IDE disables the spock transform for its editor (eclipse does this) and
so the call works out to {{MockingApi#Stub(Closure)}}, which could be enhanced
to: {{public <T> T Stub(@ClosureParams(value=FromString,options="T")
@DelegatesTo(type="T",strategy=Closure.DELEGATE_FIRST) Closure interactions)}}
-- I don't see the delegate or resolve strategy setting, but I do see the
argument passing (in GroovyRuntimeUtil#invokeClosure).
# The IDE runs the spock transform and so the call expression is transformed
into {{this.StubImpl("foo", Foo.class, \{ ... \})}} from {{SpecInternals}}. If
these methods were similarly annotated then you would get improved inferencing.
> Ability to `@DelegatesTo` the return type

> URL: https://issues.apache.org/jira/browse/GROOVY-11168
> Project: Groovy
> Issue Type: Improvement
> Reporter: Björn Kautler

> Priority: Major

>
> With a method
> {code:java}
> public <T> T Stub(Closure interactions); {code}
> that is then used like
> {code:java}
> Foo foo = Stub { /* configure the foo here */ } {code}
> I'd like to be able to specify that the delegate is of type {{T}} so in the
> given example of type {{{}Foo{}}}.
> Currently we do this in Spock via IDE-specific gdsl/dsld Scripts.
> But it would be nice if this would be supported out of the box.
> (Ideally in 2.5 already, as we still have a 2.5 compatible artifact. :))
