构造一个
std::basic_stringbuf对象初始化基类的默认构造函数调用std::basic_streambuf，初始化一个空字符串的字符序列，并设置模式which的原文：
Constructs a
std::basic_stringbuf object: initializes the base class by calling the default constructor of std::basic_streambuf, initializes the character sequence with an empty string, and sets the mode to which.2)
构造一个
.std::basic_stringbuf对象执行相同的初始化为1），然后初始化相应的字符序列，如果通过调用<div class="t-tr-text">STR（new_str）原文：
str(new_str)

拷贝构造函数被删除;
std::basic_stringbuf是不CopyConstructible原文：
The copy constructor is deleted;
std::basic_stringbuf is not CopyConstructible4)
移动构建了一个移动的所有状态从另一个
std::basic_stringbuf对象的std::basic_stringbuf，包括相关的字符串，开模，和所有其他国家的语言环境，rhs对象。六指针后移，std::basic_streambuf在*this保证不同，相应的指针移离rhs，除非空.原文：
Move-constructs a
std::basic_stringbuf object by moving all state from another std::basic_stringbuf object rhs, including the associated string, the open mode, the locale, and all other state. After the move, the six pointers of std::basic_streambuf in *this are guaranteed to be different from the corresponding pointers in the moved-from rhs unless null.目录 |

[编辑] 注释
std::basic_stringstream的构造函数通常被称为.
原文：
Typically called by the constructor of std::basic_stringstream.
支持的开放模式以外std::ios_base::instd::ios_base::out的水平不同的实现。 C + +11中明确规定的支持std::ios_base::ate
str()，并在此构造函数，但std::ios_base::app，std::ios_base::trunc，std::ios_base::binary有不同的影响，在不同的实现.原文：
The level of support for the open modes other than std::ios_base::in and std::ios_base::out varies among implementations. C++11 explicitly specifies the support for std::ios_base::ate in
str() and in this constructor, but std::ios_base::app, std::ios_base::trunc, and std::ios_base::binary have different effects on different implementations.[编辑] 示例
演示如何直接调用构造函数的basic_stringbuf .
原文：
Demonstrates calling the constructor of basic_stringbuf directly.
#include <iostream> #include <sstream> int main() { // default constructor (mode = in|out) std::stringbuf buf1; buf1.sputc('1'); std::cout << &buf1 << '\n'; // string constructor in at-end mode (C++11) std::stringbuf buf2("test", std::ios_base::in | std::ios_base::out | std::ios_base::ate); buf2.sputc('1'); std::cout << &buf2 << '\n'; // append mode test (results differ among compilers) std::stringbuf buf3("test", std::ios_base::in | std::ios_base::out | std::ios_base::app); buf3.sputc('1'); buf3.pubseekpos(1); buf3.sputc('2'); std::cout << &buf3 << '\n'; }
