class strstream : public std::iostream |
(已弃用) | |
类
strstream
实现阵列支持数据流的输入和输出操作。它实质上是封装了一组原始I / O设备实现(std::strstreambuf)进入更高层次的接口std::basic_iostream. 原文:
The class
strstream
implements input and output operations on array-backed streams. It essentially wraps a raw array I/O device implementation (std::strstreambuf) into the higher-level interface of std::basic_iostream. 典型的实现
strstream
持有非衍生只有一个数据成员:一个对象类型std::strstreambuf.原文:
The typical implementation of
strstream
holds only one non-derived data member: an object of type std::strstreambuf.[编辑] 成员函数
