path& operator=(const path& p);
Effects: If *this and p are the same object, has no effect.
Otherwise, sets both respective pathnames of *this to the respective pathnames of p.
Returns: *this.
path& operator=(path&& p) noexcept;
Effects: If *this and p are the same object, has no effect.
Otherwise, sets both respective pathnames of *this to the respective pathnames of p.
p is left in a valid but unspecified state.
[Note
:
A valid implementation is swap(p).
end note
]
Returns: *this.
path& operator=(string_type&& source); path& assign(string_type&& source);
Effects: Sets the pathname in the detected-format of source to the original value of source.
source is left in a valid but unspecified state.
Returns: *this.
template <class Source> path& operator=(const Source& source); template <class Source> path& assign(const Source& source); template <class InputIterator> path& assign(InputIterator first, InputIterator last);
Effects: Let s be the effective range of source ([fs.path.req]) or the range [first, last), with the encoding converted if required ([fs.path.cvt]).
Finds the detected-format of s ([fs.path.fmt.cvt]) and sets the pathname in that format to s.
Returns: *this.
