NAME¶

std::auto_ptr::operatorauto_ptr - std::auto_ptr::operatorauto_ptr

Synopsis¶

template< class Y > (1) (deprecated in C++11)
operator auto_ptr_ref<Y>() throw(); (removed in C++17)
template< class Y > (2) (deprecated in C++11)
operator auto_ptr<Y>() throw(); (removed in C++17)

Converts *this to an auto_ptr for a different type Y.

1) Returns an implementation-defined type that holds a reference to *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.
2) Constructs a new auto_ptr with a pointer obtained by calling release().

Parameters¶

(none)

Return value¶

1) An implementation-defined type that holds a reference to *this.
2) An auto_ptr with a pointer obtained by calling release().

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.
