Re: Eclipse Problems

[Greg Hogan]

Matthias,

Won't this be a compile-time error as long as the user is parameterizing
the return type since .fromElements(OUT...) returns DataStreamSource
and will bind to the nearest common superclass? The new
.fromElements(Class, OUT...) does give the user the choice of common
superclass.

Re: Eclipse Problems

[Matthias J. Sax]

I guess, removing .fromElements(Object..) would fix the problem. Not
sure so, if we can remove the method due to API stability...

I don't see any other good solution (even if the current implementation
gives a nice behavior by accident...):

If you have a complex class hierarchy, it would be quite complex to find
out the correct common sub-type. Using only .fromElemenst(Class,
X...) requires to specify the correct sub-type and has the additional
advantage, the the compiler can check the type already (instead of a
potential later runtime error).

Re: Eclipse Problems

[Till Rohrmann]

You’re completely right Mathias. The compiler shouldn’t allow something
like env.fromElements(SubClass.class, new ParentClass()) if it weren’t for
the overloaded method. Thus, the test case is somewhat bogus.

I’m actually wondering why the initial problem
https://issues.apache.org/jira/browse/FLINK-3444 was solved this way. I
think it would be better to automatically infer the common super type of
all provided elements. Otherwise, you run into problems you’ve found out
about.

Consequently, I think it is fine if you remove the fromElementsWithBaseType2
test case.

Cheers,
Till

Re: Eclipse Problems

[Matthias J. Sax]

Hi Till,

but StreamExecutionEnvironmentTest.fromElementWithBaseTypeTest2 does not
test was you describe -- even if it is intended to test it.

It would test your describe scenario, if fromElements(Class, X...)
would be called, But this call is not possible because X is defined a
type Subclass and thus the provided object of Parentclass cannot be
handed over as type X. Therefore, fromElements(Object...) is called: of
course, this fails too, because now the type is derived as
Class (and not Subclass) and neither Subclass nor Parentclass
inherit from Class.

The scenario you describe will never work -- if you remove the overload
fromElements(Object...) the code would not even compile as the compiler
can figure out from the generics that the call
fromElments(Subclass.class, new Parentclass()) is invalid.

It is only possible to hand in "reverse inheritance types" for
fromElemenst(Object...). In this case, the first given Object defines
the type. Thus, if you call fromElements(new Subclass(), new
Parentclass()), the call will fail, as Parentclass is no subtype of
Subtype -- the call fromElements(new Parentclass() new Subclass()) would
succeed.

Makes sense?

Still no idea how to make it compile in Eclipse...

Re: Eclipse Problems

[Matthias J. Sax]

Even if the fix works, I still have two issues in my Eclipse build...

In

flink-scala/src/test/scala/org/apache/flink/api/scala/extensions/base/AcceptPFTestBase.scala

Eclipse cannot infer the integer type. It could be fixed if you make the
type explicit (as this is only a test, it might be nice to fix this --
let me know if I can push this or not)

In both cases, I get the error:

  The method .fromElements(Object[]) is ambiguous

No clue how to fix this, and why Eclipse does not bind to
.fromElements(Class, X). Any ideas?

I also digger a little bit and for both test-classes there is a second
test method called "fromElementsWithBaseTypeTest2". If I understand this
test correctly, it also tries to bind to .fromElements(Class, X), but
this does not happen and .fromElemenst(Object[]) is called. Even if
there is still an exception, I got the impression that this test does
not what the intention was.

If might be good to change fromElementsWithBaseTypeTest2 to

(ie, remove the first Class parameter). Any comments on this?

 Hey Matthias!

 Thanks for bringing this up.

 I think it is very desirable to keep support for Eclipse. It's quite a
 high barrier for new contributors to enforce a specific IDE (although
 IntelliJ is gaining quite the user base I think :P).

 Do you have time to look into this?
