This is still an experimental attribute, but I wanted it in tree for review. It may still get yanked. This attribute can only be applied to a class @interface, not a class extension or category. It does not change the type system rules for Objective-C, but rather the implementation checking for Objective-C classes that explicitly conform to a protocol. During protocol conformance checking, clang recursively searches up the class hierarchy for the set of methods that compose a protocol. This attribute will cause the compiler to not consider the methods contributed by a super class, its categories, and those from its ancestor classes. Thus this attribute is used to force subclasses to redeclare (and hopefully re-implement) methods if they decide to explicitly conform to a protocol where some of those methods may be provided by a super class. This attribute intentionally leaves out properties, which are associated with state. This attribute only considers methods (at least right now) that are non-property accessors. These represent methods that "do something" as dictated by the protocol. This may be further refined, and this should be considered a WIP until documentation gets written or this gets removed. llvm-svn: 195533 |
