Constructs a new directory_entry
object.
1) Default constructor.
2) Defaulted copy constructor.
3) Defaulted move constructor.
4) 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
The overload that does not take a std::error_code&
parameter throws 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. The overload taking a std::error_code&
parameter sets it to the OS API error code if an OS API call fails, and executes ec.clear()
if no errors occur. Any overload not marked noexcept
may throw std::bad_alloc
if memory allocation fails.
