Typed object-oriented programming languages, such as Java and C++, often do not support first-class methods.〔Shroff & Smith〕 Smalltalk only support them in an untyped way 〔Shroff & Smith〕 In Objective-C (Cocoa), you can use NSInvocation to represent first-class messages in a way that is aware of the types at runtime; however, safe use still relies on the programmer. Some theoretical progress has been made to support first-class messages in a type-safe manner, but none of the proposed systems has been implemented in a programming language, possibly due to their complexity.〔Shroff & Smith〕 == See also == * Delegate (object-oriented programming) * First-class function 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「First-class message」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
