[架構(gòu)設(shè)計(jì)]設(shè)計(jì)模式C++實(shí)現(xiàn)--適配器模式

1、模式定義:適配器模式將一個(gè)類的接口，轉(zhuǎn)換成客戶期望的另一個(gè)接口。適配器讓原本接口不兼容的類可以合作無(wú)間。適配器可以分為類適配器和對(duì)象適配器。類適配器使用多重繼承對(duì)一個(gè)接口與另一個(gè)接口進(jìn)行匹配。對(duì)象適配器依賴于對(duì)象組合。客戶使用適配器的過程:1.客戶通過目標(biāo)接口調(diào)用適配器的方法對(duì)適配器發(fā)出請(qǐng)求。2.適配器使用被適配者接口把請(qǐng)求轉(zhuǎn)換成被施培者的一個(gè)或多個(gè)調(diào) 用接口3.客戶接收到調(diào)用的結(jié)果，但并未察覺這一切是適配器在起轉(zhuǎn)換作 用。模式結(jié)構(gòu):類適配器對(duì)象適配器舉例:現(xiàn)在假設(shè)你缺少鴨子對(duì)象（叫聲為Quack,飛行輸出”1 ' m flying !，想用一些火雞對(duì)象（叫聲為” Gobble gob
