operators (std::filesystem::path)

运算符<<，>%28 std：：file system：：path%29

template< class CharT, class Traits > std::basic_ostream& operator<<( std::basic_ostream& os, const path& p (1)(since C++17)
template< class CharT, class Traits > std::basic_istream<CharT,Traits>& operator>>( std::basic_istream<CharT,Traits>& is, path& p (2)(since C++17)

在路径上执行流输入或输出。p...std::quoted用于使空格在以后由流输入运算符读取时不会被截断。

参数

os-stream to perform output on
is-stream to perform input on
p-path to insert or extract

返回值

1%29os

2%29is

例外

%280%29

可能的实施

第一版

*。

模板<类图表，类特征>std：：basic[医]<图表，性状>&操作符<%28 STD：基本[医]<图表，特征>&os，Const路径&p%29{os<<std：引号%28 P字符串<图表，字符>%28%29%29；返回os；}

第二版

模板<类图表，类特征>std：：basic[医]iStream<图表、性状>和操作员>>%28 STD：基本[医]iStream<图表、性状>&is，path&p%29{std：：basic[医]字符串<图表，特征>t；is>>std：：引号%28t%29；p=t；返回is；}
