怎樣理解C++中的Aggregate和POD類型

無論是 Aggregate 還是 POD（Aggregates的升級(jí)版）都是對(duì)用來約束初始化的精巧的概念。

motivation

當(dāng)我們欲構(gòu)造如下的union時(shí)：

union{ int i; std::string s;  

 // illegal: std::string is not a POD type!} u;

vs 2013會(huì)對(duì)之作進(jìn)一步的錯(cuò)誤說明：

error C2621: “::s”: 非法的聯(lián)合成員；

類型“std::basic_string,std::allocator>”具有復(fù)制構(gòu)造函數(shù) 

兩者一規(guī)約，也即POD數(shù)據(jù)類型不允許使用其具有復(fù)制構(gòu)造函數(shù)； 

而且我們還可看到： 

所謂的std::string類型其實(shí)是對(duì)std::basic_string<>某一特化版本的類型定義：

typedef basic_string, allocator > string;

解釋：Aggregates vs POD

如果想深入了解 POD（Plain Old Data）的話，了解 aggregates（聚合，集成？） 是必須的。

首先我們來看C++標(biāo)準(zhǔn)對(duì) aggregates 的定義：

An aggregate is an array or a class (clause 9) with no user-declared constructors (12.1), no private or protected non-static data members (clause 11), no base classes (clause 10), and no virtual functions (10.3).

也即，首先所有的數(shù)組都是Aggregates，然后類類型如果滿足那四個(gè)條件，等等，標(biāo)準(zhǔn)未對(duì)結(jié)構(gòu)體（structs）以及聯(lián)合體（unions）做任何說明。難道它們就不能成為aggregates了嗎？可以的。在C++中，術(shù)語（關(guān)鍵字） class 表示所有的類、結(jié)構(gòu)體以及聯(lián)合。

那么，這四條關(guān)于類（class）的約束說明了：

并非意味著一個(gè) aggregate class 不可以擁有構(gòu)造函數(shù)，事實(shí)上，它們可以擁有一個(gè)默認(rèn)構(gòu)造函數(shù)（default constrctor）以及（或者）一個(gè)拷貝構(gòu)造函數(shù)只有它們被編譯器隱式地聲明，而非被用戶顯式地聲明。

no private or protected non-static data members。You can have as many private and protected member functions (but not constructors) as well as as many private or protected static data members and member functions as you like and not violate the rules for aggregate classes。靜態(tài)成員可以出現(xiàn)在任何位置，非靜態(tài)成員只得以公共成員（public）的形式出現(xiàn)。

An aggregate class can have a user-declared/user-defined copy-assignment operator and/or destructor。結(jié)合第一條，也即如果想要出現(xiàn)構(gòu)造函數(shù)的話，必須以拷貝構(gòu)造的形式出現(xiàn)（operator=），

An array is an aggregate even if it is an array of non-aggregate class type.

下面我們來看一些具體的例子：

class NotAggregate1{    virtual void f() {}    // no virtual functions};class NotAggregate2{    int x;                 // x is private by default and non-static    };class NotAggregate3{public:    NotAggregate3(int) {}   // user-defined ctor    };class Aggregate1{public:    NotAggregate1 member1;                                    // ok, public member    Aggregate1& operator(const Aggregate1& rhs) {// }                                // ok, copy-assignmentprivate:    void f() {}                                // ok, non-virtual function};

現(xiàn)在我們來說明，為什么會(huì)提出 Aggregate 這樣一個(gè)概念以及它是如何跟 POD（Plain Old Data）發(fā)生關(guān)聯(lián)的？Aggregate 類型的類，可以被初始化通過 {}，而non-Aggregate 的 class 不可以。

（提出這樣一個(gè)概念，是為了規(guī)范化初始化的用法）：

struct X{    int i1;    int i2;};struct Y{    char c;    X x;    int i[2];    float f;protected:    static double d;    Y& operator=(const Y& rhs) { return *this};private:    void g(){}};

我們可直接使用{}進(jìn)行初始化：

Y y = {'a', {10, 10}, {20, 30}};            // y.c = 'a'            // y.x.i1 = 10            // y.x.i2 = 10            // y.i[0] = 20            // y.i[1] = 30            // y.f = 0.0 by value-initialized 的方式            // d 未被初始化，因?yàn)樗庆o態(tài)的

POD

來自C++標(biāo)準(zhǔn)：

A POD-struct is an aggregate class that has no non-static data members of type non-POD-struct, non-POD-union (or array of such types) or reference, and has no user-defined copy assignment operator and no user-defined destructor. Similarly, a POD-union is an aggregate union that has no non-static data members of type non-POD-struct, non-POD-union (or array of such types) or reference, and has no user-defined copy assignment operator and no user-defined destructor. A POD class is a class that is either a POD-struct or a POD-union. 

An aggregate class is called a POD if it has no user-defined copy-assignment operator and destructor and none of its nonstatic members is a non-POD class, array of non-POD, or a reference.

所有的POD類都必須是Aggregate，或者說，一個(gè)類如果不是Aggregate，則一定不是POD類（兩者成逆否命題）。

和 Aggregates 的情況一樣，靜態(tài)成員不在乎其具體是什么樣的類型（只要是靜態(tài)的即可）

詞根 ‘LEGA’ 和 ‘GREG’

每日知識(shí)探索，與您共享深厚詞根的魅力—— LEGA與GREG的深度解析

DAY 97

讓我們一同探索詞根的神奇世界，今天聚焦于LEGA與GREG，這兩個(gè)詞根蘊(yùn)含著豐富的含義和詞匯擴(kuò)展。

詞根LEGA，象征著“任命，**”，它在詞匯中留下了獨(dú)特的印記：

legate ['legət]，作為動(dòng)詞后綴，意為羅馬教皇的使節(jié)或使者，承載著使命和傳遞的信息。同時(shí)，它也延伸為“當(dāng)做遺產(chǎn)讓與”，體現(xiàn)了權(quán)力和傳承的意義。

legacy ['lɛgəsi]，作為名詞后綴，是指留下的遺產(chǎn)，不僅是物質(zhì)財(cái)富，更包括精神和價(jià)值觀的傳遞。

delegation ['dɛlɪ'ɡeʃən]，代表著代表團(tuán)或委托，體現(xiàn)了權(quán)力的委派和責(zé)任的轉(zhuǎn)移。

而當(dāng)LEGA與"re-"結(jié)合，我們得到的是relegation，意味著貶謫、驅(qū)逐或歸屬的改變，展現(xiàn)了權(quán)力和地位的動(dòng)態(tài)變化。

接下來，我們關(guān)注的是另一個(gè)詞根GREG，它的核心概念是“一群”：

aggregate ['æɡrɪɡət]，強(qiáng)調(diào)的是聚集和合計(jì)，無論是數(shù)字還是人群，都體現(xiàn)了集合的力量。

congregation ['kɑŋɡrɪ'ɡeʃən]，指代的是大規(guī)模的集會(huì)、集合，或是宗教團(tuán)體，體現(xiàn)了團(tuán)結(jié)和群體的凝聚力。

當(dāng)GREG與"e-"和"ous"結(jié)合，我們得到的是egregious，形容詞，意味著驚人的、過分的或惡名昭彰的，強(qiáng)調(diào)的是極端或異常的群體特性。

segregate ['sɛɡrɪɡet]，則表示使隔離或分離，反映出社會(huì)、群體中個(gè)體的劃分或矛盾。

詞根LEGA與GREG，如同語言的種子，從古至今，孕育出無數(shù)豐富多樣的詞匯，展現(xiàn)了語言的博大精深。了解它們，就如同打開了一扇通向古老智慧的大門。
