NAME¶

std::filesystem::path::assign - std::filesystem::path::assign

Synopsis¶

path& assign( string_type&& source ); (1) (since C++17)
template< class Source > (2) (since C++17)
path& assign( const Source& source );
template< class InputIt > (3) (since C++17)
path& assign( InputIt first, InputIt last );

Replaces the contents to the path object by a new pathname constructed from the
given character sequence.

1) Assigns the pathname identified by the detected-format string source, which is
left in valid, but unspecified state.
2) Assigns the pathname identified by the detected-format character range source.
3) Assigns the pathname identified by detected-format character range [first, last).

(2) participates in overload resolution only if Source and path are not the same
type, and either:

* Source is a specialization of std::basic_string or std::basic_string_view, or
* std::iterator_traits<std::decay_t<Source>>::value_type is valid and denotes a
possibly const-qualified encoding character type (char,
char8_t,
(since C++20)char16_t, char32_t, or wchar_t).

Parameters¶

a character range to use, represented as std::string,
source - std::string_view, pointer to a null-terminated multibyte string, or as
an input iterator with char value type that points to a
null-terminated multibyte string
first, last - a character range to use

Type requirements¶

-
InputIt must meet the requirements of LegacyInputIterator.
-
The value type of InputIt must be one of the encoded character types (char, wchar_t,
char16_t and char32_t)

Return value¶

*this
