29.12.10.3 Modifiers [fs.dir.entry.mods]

void assign(const filesystem::path& p); void assign(const filesystem::path& p, error_code& ec);
Effects: Equivalent to pathobject = p, then refresh() or refresh(ec), respectively.
If an error occurs, the values of any cached attributes are unspecified.
Throws: As specified in [fs.err.report].
void replace_filename(const filesystem::path& p); void replace_filename(const filesystem::path& p, error_code& ec);
Effects: Equivalent to pathobject.replace_­filename(p), then refresh() or refresh(ec), respectively.
If an error occurs, the values of any cached attributes are unspecified.
Throws: As specified in [fs.err.report].
void refresh(); void refresh(error_code& ec) noexcept;
Effects: Stores the current values of any cached attributes of the file p resolves to.
If an error occurs, an error is reported ([fs.err.report]) and the values of any cached attributes are unspecified.
Throws: As specified in [fs.err.report].
[Note 1:
Implementations of directory_­iterator ([fs.class.directory.iterator]) are prohibited from directly or indirectly calling the refresh function as described in [fs.class.directory.iterator.general].
