Moderne licensed

Use lambda expressions instead of anonymous classes

Recipe IDorg.openrewrite.staticanalysis.UseLambdaForFunctionalInterfaceArtifactorg.openrewrite.recipe:rewrite-static-analysis

Instead of anonymous class declarations, use a lambda where possible. Using lambdas to replace anonymous classes can lead to more expressive and maintainable code, improve code readability, reduce code duplication, and achieve better performance in some cases.

Structured output this recipe can produce.

Anonymous functional interface implementationsEvery anonymous class that implements a functional interface, whether or not it could be rewritten to a lambda, plus the sites that could not be decided either way because the supertype carries incomplete type attribution.
