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 overload participates in overload resolution only if W2* is convertible to element_type*.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
