在C ++中，构造函数和析构函数可以是内联函数吗？ [英] In C++ can constructor and destructor be inline functions?

问题描述

如果我声明一个类 Foo 如下，那么是CONSTRUCTOR和DESTRUCTOR内联函数？

  class Foo 
 {
 int * p ; 
 public：
 Foo（）{p = new char [0x00100000]; } 
〜Foo（）{delete [] p; } 
}; 
 
 {
 Foo f; 
（f）; 
} 
  

解决方案

定义构造函数INSIDE在类中使用inline关键字放置函数OUTSIDE的效果相同。

在这两种情况下，它都是编译器的提示。 内联函数不一定意味着函数将被内联。这取决于函数的复杂性和其他规则。

VC++ makes functions which are implemented within the class declaration inline functions.

If I declare a class Foo as follows, then are the CONSTRUCTOR and DESTRUCTOR inline functions?

class Foo 
{
    int* p;
public:
    Foo() { p = new char[0x00100000]; }
    ~Foo() { delete [] p; }
};

{
    Foo f;
    (f);
}

解决方案

Defining the body of the constructor INSIDE the class has the same effect of placing the function OUTSIDE the class with the "inline" keyword.

In both cases it's a hint to the compiler. An "inline" function doesn't necessarily mean the function will be inlined. That depends on the complexity of the function and other rules.
