Guru of the Week 條款30附錄:介面原則

它是這麼工作的:所謂“名稱搜尋”就是當你寫下一個“f(parm)”呼叫時,編譯器必須要決策出你想調哪個叫f的函式。(由於過載和作用域的原因,可能會有幾個叫f的函式。)Koenig lookup是這麼說的,如果你傳給函式一個class型別的實參(此處是parm,型別為NS::T),為了查詢這個函式名,編譯器被要求不僅要搜尋如區域性作用域這樣的常規空間,還要搜尋包含實參型別的名稱空間(此處是NS)〖注5〗。於是,Example 3 (a)中是這樣的:傳給f的引數型別為T,T定義於namespace NS,編譯器要考慮namespace NS中的f--不要大驚小怪了。
