std::auto_ptr<T>::operator auto_ptr<Y>
template< class Y > operator auto_ptr_ref<Y>() throw(); |
(1) | (deprecated in C++11) (removed in C++17) |
template< class Y > operator auto_ptr<Y>() throw(); |
(2) | (deprecated in C++11) (removed in C++17) |
Converts *this
to an auto_ptr
for a different type Y
.
*this
.
std::auto_ptr
is
convertible and
assignable from this template. The implementation is allowed to provide the template with a different name or implement equivalent functionality in other ways.
Parameters
(none).
Return value
*this
Notes
The constructor and the copy assignment operator from auto_ptr_ref
is provided to allow copy-constructing and assigning std::auto_ptr
from nameless temporaries. Since its copy constructor and copy assignment operator take the argument as non-const reference, they cannot bind rvalue arguments directly. However, a user-defined conversion can be executed (which releases the original auto_ptr), followed by a call to the constructor or copy-assignment operator that take auto_ptr_ref
by value. This is an early implementation of move semantics.
