1) Constructs an
observer_ptr that has no corresponding watched object.
2) Constructs an
observer_ptr that watches p.
3) Constructs an
observer_ptr that watches other.get(). This constructor does not participate in overload resolution unless W2* is convertible to W*.
4-5) Implicitly declared copy and move constructors. Constructs an
observer_ptr that watches other.get().[edit] Parameters
| p | - | a pointer to an object to watch |
| other | - | another observer_ptr to copy from
