directory_iterator

成員函式

directory_iterator::directory_iterator

directory_iterator::operator*directory_iterator::operator->

directory_iterator::operator=

directory_iterator::incrementdirectory_iterator::operator++

非成員函式

begin(directory_iterator)end(directory_iterator)

 

directory_iterator begin( directory_iterator iter );	(1)	(filesystem TS)
directory_iterator end( const directory_iterator& );	(2)	(filesystem TS)

1) 返回iter不變。

2) 返回一個預設構造的 directory_iterator，作為結束迭代器。引數被忽略。

這些非成員函式使得 directory_iterator 可以與基於範圍的 for 迴圈一起使用。

引數

iter

-

一個 directory_iterator

返回值

1) iter 不變。

2) 結束迭代器（預設構造的 directory_iterator）。

異常

noexcept 規範：  

無異常

  

示例

執行此程式碼

#include <experimental/filesystem>
#include <fstream>
#include <iostream>
namespace fs = std::experimental::filesystem;
 
int main()
{
    fs::create_directories("sandbox/a/b");
    std::ofstream("sandbox/file1.txt");
    std::ofstream("sandbox/file2.txt");
    for (auto& p : fs::directory_iterator("sandbox"))
        std::cout << p << '\n';
    fs::remove_all("sandbox");
}

可能的輸出

"sandbox/a"
"sandbox/file1.txt"
"sandbox/file2.txt"
