awt-related types that are candidates to be FunctionalInterfaces in JDK 8 (original) (raw)

Hello,

As part of Project Lambda, a FunctionalInterface annotation type was added to the platform to mark interfaces that are intended to be used in lambda expressions. I've sent out a code review request to add this annotation to types in the core-libs area [1].

To assist the awt team in adding analogous annotations to your types, the list of candidate types in for awt-related classes in java.* and javax.* is given below. I recommend sub-tasks of JDK-8005297 "Add FunctionalInterface support to the platform" be used to track the work of adding @FunctionalInterface annotations to awt types.

Thanks,

-Joe
