std::ostreambuf_iterator::ostreambuf_iterator
STD：：OStreambuf[医]迭代器：：[医]迭代器
| ostreambuf_iterator( streambuf_type* buffer | (1) | |
|---|---|---|
| ostreambuf_iterator( ostream_type& stream | (2) | |
1%29使用私有构造迭代器。streambuf_type*成员设置为buffer失败的%28%29位设置为false如果buffer为空指针。
2%29ostreambuf_iterator(stream.rdbuf())
参数
| stream | - | the output stream whose rdbuf() will be accessed by this iterator |
|---|---|---|
| buffer | - | the output stream buffer to be accessed by this iterator |
例外
| (none) | (until C++11) |
|---|---|
| noexcept specification: noexcept | (since C++11) |
例
二次
#include <iostream>
#include <fstream>
#include <iterator>
int main()
{
std::basic_filebuf<char> f;
f.open("test.txt", std::ios::out
std::ostreambuf_iterator<char> out1(&f
std::ostreambuf_iterator<wchar_t> out2(std::wcout
*out1 = 'a';
*out2 = L'a';
}
