explicit logic_error( const std::string& what_arg ); (1) explicit logic_error( const char* what_arg ); (2) (C++11 起) 以what_arg 为解释字符串构造异常对象,能通过 what() 访问它。 因为不容许复制 std::logic_error 抛出异常,通常将此消息在内部存储为分离分配的引用计数字符串。这也是构...

exception基类不包含以string为参数的构造函数,所以,不能throw exception(“Error”);一般不从这个根类直接继承,从下面的派生类继承。 error: no matching function for call to ‘std::exception::exception(const char [4])’ 改成: std::logic_error e("Invalid param"); throw std::exception(e); excepti...

std::string getUUID(); 这是Message.cpp中相应的实现: 代码语言:javascript 复制 #include "Message.hpp" #include <iostream> #include <string> #ifdef HAVE_UUID #include <uuid/uuid.h> #endif std::ostream &Message::printObject(std::ostream &os) { ...
2...2.3 显式声明拷贝构造函数 首先看只显式声明一个拷贝构造函数的情况,如下: #include #include using namespace std;...显示声明普通构造函数和拷贝构造函数时,会自动生成移动构造函数; 这些构造函数不要求总是全部显式声明,但我们在使用class的时候最好显式声明这五种构造函数,避免出现一些不必要的问题。 1.2...
