nub::soft_ref<T> is a ref-counted smart pointer (like nub::ref<T>) for holding ref_counted objects. Construction of a nub::soft_ref<T> is guaranteed not to fail. Because of this, however, a nub::soft_ref<T> is not guaranteed to always point to a valid object (this must be tested with is_valid() before dereferencing). With these characteristics, a nub::soft_ref<T> can be used with volatile ref_counted objects for which only weak references are available.

Returns the pointee, or if throws an exception if there is not a valid pointee.

| T* nub::soft_ref< T >::get_weak | ( | ) | const throw () [inline] |
Returns the pointee, or returns null if there is not a valid pointee. Will not throw an exception.

Shorthand for assignment.
Given ref<T> rr and T* p, then rr.reset(p) is shorthand for rr=ref<T>(p). But of course, rr.reset(p) is much less typing if T happens to be spelt SomeLongType<WithTemplateParams>.
