I tried to implement anonymous Comparator class, thus I wrote following code: private Comparator<PolicyAssertion> assertionComparator = new Comparator<PolicyAssertion>() { }; The parser correctly recognized missing method implementation and it provided a code completion hint to implement all abstract methods, which resulted into following code: private Comparator<PolicyAssertion> aassertionComparator = new Comparator<PolicyAssertion>() { public int compare(Object o1, Object o2) { } }; ...which is wrong and parser recognizes this error underlyning the code-completed method. Proper method signature should have PolicyAssertion input parameters: public int compare(PolicyAssertion o1, PolicyAssertion o2) { }
So the problem is after Alt+Enter and clicking "Implement all abstract methods", right? It seems that the java hints provider does not care about generics properly. The code should be in java/hints I guess ImplementMethodJavaHint. Reassigning to Vita. Adding jlahoda to cc as Honza knows the editor hints best.
I've spent some time investigating the problem and here is what I found. The hint seems to work fine for normal classes no matter whether they use generics or not. However, it's broken for annonymous classes. For some reason the ClassDefinition of an annonymous class doesn't seem to know about the generics. When it's asked to return interfaces implemented by the annonymous class it simply returns interfaces without the generics type. In the example mentioned in this defect the ClassDefinition of the annonymous class returns java.lang.Comparator as the implemented interface. When the same example is used for non-annonymous class the ClassDefinition returns java.lang.Comparator<whatever.package.PolicyAssertion> JavaClass and the provided hint works fine. Now, I admit that I do not understand how the java model is implemented, but my impression is that the defect is not in the java hints provider, but in the java model implementation itself. Any pointers please?
Reassigning to java module.
we will look at it. The problem is in javacore.
