inout_ptr_t( const inout_ptr_t& ) = delete; |
(2) | (since C++23) |
1) Creates an
inout_ptr_t
. Adapts sp
as if binds it to the Smart& member, captures every argument t
in args...
as if initializes the corresponding member of type T
in Args...
with std::forward<T>(t), then initializes the stored Pointer
with sp
if Smart
is a pointer type, otherwise, initializes it with sp.get(). sp.release() may be called if Smart
is not a pointer type, in which case it will not be called again within the destructor.2) Copy constructor is explicitly deleted.
inout_ptr_t
is neither copyable nor movable.Parameters
sp | - | the object (typically a smart pointer) to adapt |
args... | - | the arguments used for resetting to capture |
Return value
(none)
Exceptions
May throw implementation-defined exceptions.
Notes
If Smart
is not a pointer type and sp.release() is not called by the constructor, it may be called by the destructor before resetting sp
.
Every argument in args...
is moved into the created inout_ptr_t
if it is of an object type, or transferred into the created inout_ptr_t
as-is if it is of a reference type.
The constructor of inout_ptr_t
is allowed to throw exceptions. For example, when sp
is an intrusive pointer with a control block, the allocation for the new control block may be performed within the constructor rather than the destructor.
