Converts
*
this
to an
auto_ptr
for a different type
Y
.
Parameters
(none)
Return value
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
(1)
or
(2)
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
.
