Regarding... *> public interface A is returning Region and not Region<K,V> is that an acceptable suppression?*
I think Geode API/Framework (e.g. PDX) (production) code should be very explicit and *not* use *rawtypes*, or even *wildcard* types, for that matter, as far as possible. To be clear, I am saying sometimes in tests, *rawtypes* are useful. Again, all of these things should be applied responsibly and judiciously, with intent, especially in production code. Use of *Java Generics* in code can cause as much grief for a user as it does help in other cases (as Jake alluded to), so it needs to be careful crafted, especially in public APIs as it affects more than test code, but even application code that might require references to Geode objects. -j On Fri, May 8, 2020 at 1:30 PM Mark Hanson <mhan...@pivotal.io> wrote: > It is slightly different, but here is a case I recently found. > > List<VersionTag> versionTags = versions.getVersionTags(); > > This method is internal though. > public List<VersionTag> getVersionTags() { > return Collections.unmodifiableList(this.versionTags); > } > > Thanks, > Mark > > > > On May 8, 2020, at 1:25 PM, Mark Hanson <mhan...@pivotal.io> wrote: > > > > How does everyone feel about situations involving raw types? > > > > Such as public interface A is returning Region and not Region<K,V> is > that an acceptable suppression? > > > > Thanks, > > Mark > > > >> On May 8, 2020, at 1:20 PM, John Blum <jb...@pivotal.io> wrote: > >> > >> Agreed, but the following (inside tests) does not work in all cases, > i.e. > >> > >> Region<String, String> region... > >> > >> Particularly if "region" is passed to a method with a different type > >> signature. > >> > >> I am trying to find/think of the situation I encounter from time to > time, > >> even when I use the *wildcard* signature (i.e. Region<?, ?>), but cannot > >> currently find it (*#ugh*). > >> > >> Anyway, the point is, if the test is really not concerned with the type > of > >> values (*keys*, *values*) being stored in the mock *Region* then > rawtypes (or > >> sometimes Region<?, ?>) are useful in some cases since the point of the > >> test is not about the data but perhaps about *Region* configuration in > >> general, so adding types detracts (adds undue noise) to the code under > test > >> (IMO). > >> > >> It depends and is subjective. > >> > >> I agree, though, in general, @SuppressWarnings should be kept to a > minimum > >> and used only when necessary. > >> > >> -j > >> > >> On Fri, May 8, 2020 at 1:09 PM Kirk Lund <kl...@apache.org> wrote: > >> > >>> Actually there is an alternative to using @SuppressWarnings for Mockito > >>> mocks: > >>> > >>> Region<String, String> region = cast(mock(Region.class)); > >>> > >>> private static <T> T cast(Object object) { > >>> return (T) object; > >>> } > >>> > >>> Personally, I'd prefer to see warnings or workarounds like above than > see > >>> lots of @SuppressWarnings littered throughout our code base.
