責(zé)任鏈模式(Chain of Responsibility Pattern)是一種行為型設(shè)計模式,它用于將請求的發(fā)送者和接收者解耦,使得多個對象都有機會處理這個請求。在責(zé)任鏈模式中,有一個請求處理鏈條,每個處理請求的對象都是一個節(jié)點,當請求進入這個鏈條時,鏈條上的節(jié)點逐一判斷是否能夠處理該請求,如果可以,則處理;否則,將請求傳遞給下一個節(jié)點,直到請求被處理為止
Chain of Responsibility定義:Chain of Responsibility(CoR) 是用一系列類(classes)試圖處理一個請求request,這些類之間是一個松散的耦合,唯一共同點是在他們之間傳遞request。也就是說,來了一個請求,A類先處理,如果沒有處理,就傳遞到B類處理,如果沒有處理,就傳遞到C類處理,就這樣象一個鏈條(chain)一樣傳遞下去。
