Description Tomas Zezula 2015-09-18 06:59:51 UTC

See screenshot: https://netbeans.org/bugzilla/attachment.cgi?id=156177
The lambda: (String s) -> "Hello " + s, "World" is not found.

As the Java 8 lambdas unlike the BGGA Java lambdas have no functional types the Lambda expression is just an implementation of an functional interface. So it should be found in find usages.

P2 as other IDEs JDev, Idea, works fine.

Refactoring handles lambda expressions, but they seem missing from the ClassIndex. Please reassign if they are part of the index, but have to be handled differently. Thanks!

The patch covers an API change adding a SearchKind for lambda implementors and Find Usages fix for the lambdas.

Patch looks good to me, I'll update the Change Method Parameters refactoring after it lands in jet-main.
