Constructs a new
directory_entry
object.
1)
Default constructor.
2)
Defaulted copy constructor.
3)
Defaulted move constructor.
4,5)
Initializes the directory entry with path
p
and calls
refresh
to update the cached attributes. If an error occurs, the non-throwing overload leaves the
directory_entry
holding a default-constructed path.
Parameters
| p | - | path to the filesystem object to which the directory entry will refer |
| ec | - | out-parameter for error reporting in the non-throwing overload |
Exceptions
Any overload not marked
noexcept
may throw
std::bad_alloc
if memory allocation fails.
1-4)
Throws
std::filesystem::filesystem_error
on underlying OS API errors, constructed with
p
as the first path argument and the OS error code as the error code argument.
5)
Sets a
std::
error_code
&
parameter to the OS API error code if an OS API call fails, and executes
ec.
clear
(
)
if no errors occur.
