void reset( RR&& r );
1) Disposes the resource by calling the deleter with the underlying resource handle if the
unique_resource owns it. The unique_resource does not own the resource after the call.2) Replaces the resource by calling (1) and then assigns the stored resource handle with std::forward <RR>(r) if std::is_nothrow_assignable_v <RS, RR> is true, otherwise std::as_const (r), where
RS is the type of stored resource handle. The unique_resource owns the resource after the call. If copy-assignment of the store resource handle throws an exception, calls del_(r), where
del is the deleter object. This overload participates in overload resolution only if the selected assignment expression assigning the stored resource handle is well-formed.
The program is ill-formed if del_(r) is ill-formed.
The behavior is undefined if del_(r) results in undefined behavior or throws an exception.
[edit] Parameters
r
-
resource handle for a new resource to manage
[edit] Return value
(none)
[edit] Exceptions
2) Any exception thrown in assigning the stored resource handle.
[edit] Notes
The mechanism ensures no leaking of resources.
