close(), is_open(), 从istream和ostream继承了很多过来, 每一个stream应该都有一个stream buffer, ios::rdbuf这个方法就提供了得到这个buffer的pointer, 而从streambuf又派生了stringbuf和filebuf, <fstream>和<sstream>中的类用 rdbuf()会得到自己的filebuf和stringbuf (这些就是暂时写的,还不清楚其实)...
stringstream s2; s2.str(s1.str());//<---就是这句s1>>s; cout<<"s1="<<s<<endl; s2>>s; cout<<"s2="<<s<<endl; 又有人说,用 s2<<s1.rdbuf(); 代替原来那句,但后果是s1的内容被清掉了。 网上找不到有关的资料,本人也对stream不熟悉。 后来...
> class basic_stringstream; The class template std::basic_stringstream implements input/output operations on memory (std::basic_string) based streams. It essentially wraps a raw string device implementation (std::basic_stringbuf) into a higher-level interface (std::basic_iostream). The complete ...
如果rdbuf()->in_avail() == -1,电话setstate(eofbit)不提取字符。 如果rdbuf()->in_avail() == 0,不提取字符。 如果rdbuf()->in_avail() > 0、提取物std::min(rdbuf()->in_avail(), count)字符并将其存储到字符数组的连续位置,该字符数组的第一个元素由s... ...
stringstream <--> stringbuf <--> string 1. 2. 3. 4. streambuf内部实现 术语说明: get相当于从流中读取数据 put相当于写入数据到流中 字符,C/C++中的char,也可以理解为字节 streambuf内部持有三个用于get的指针gfirst,gnext,glast和三个用于put的指针pfirst,pnext,plast,这些指针分别可以使用eback(),...
要将内存块数据插入到`std::iostream`或`std::istream`中,可以采取以下方法。首先,创建一个`std::stringstream`对象`gangplank`,然后利用`std::iostream`的`rdbuf()`函数将其与输入流连接起来,如下所示:如果你需要对数据进行gzip压缩或解压缩,可以使用boost::iostreams库,先将gzip压缩/解压缩器...
