Let t_
designate the private data member that is the wrapped pointer-like object.
1) Explicitly defaulted move assignment operator that move assigns this->t_ from p.t_
2) Assigns std::move(pu.t_) to this->t_.
This overload participates in overload resolution only if
This overload participates in overload resolution only if
U
is implicitly convertible to T
3) Assigns
std::forward
<U>
(u)
to this->t_.
This overload participates in overload resolution only if
This overload participates in overload resolution only if
U
is implicitly convertible to T
and
std::decay_t<U>
is not a specialization of propagate_const
4) Copy assignment operator is explicitly deleted.
propagate_const
is non-copyable.Parameters
p | - | another propagate_const object to move from
|
pu | - | another propagate_const object of a different specialization to move from
|
u | - | another object to assign to the contained pointer |
Return value
*this.
