1、設(shè)計(jì)模式 C+學(xué)習(xí)筆記之十五（Comite 組合模式）15.1.解釋概念：將對(duì)象組樹形結(jié)構(gòu)以表示“部分-整體”的層次結(jié)構(gòu)。Com使用具有一致性。ite 使得用戶對(duì)單個(gè)對(duì)象和組合的main()，客戶CCorpNode，抽象基類，實(shí)現(xiàn)基本信息CBranchNode，樹枝節(jié)點(diǎn)，實(shí)現(xiàn) Addordinate()函數(shù)和 GetSubordinate()函數(shù)CLeafNode，葉子節(jié)點(diǎn)，IsLeaf 屬性總是“true”說明：組合模式主要是實(shí)現(xiàn)在 CBranchNode 對(duì)象里增加對(duì)其它對(duì)象的數(shù)組，如 vector，數(shù)組里可以存放CBranchNode 和CLeafNode 對(duì)象。這樣方便進(jìn)行遍歷操作。注

2、意：組合模式有透明組合模式和安全組合模式。透明組合模式是將Addordinate 和GetSubordinate這兩個(gè)函數(shù)也抽象到CCorpNode 基類里，這增加了操作葉子節(jié)點(diǎn)的難度，更易出現(xiàn)邏輯問題。所以盡量使用安全模式。這個(gè)簡單了，可以想像一下TreeView 和 TreeNode 基本上是這個(gè)意思了，將很多數(shù)據(jù)組織在一塊。看代碼：/CorpNode.h#pragma once #include using std:string; class CCorpNodepublic:CCorpNode();CCorpNode(string _name, string _ virtual CCor
