Detailed Description

template<class T>
class nub::ref< T >

nub::ref<T> is a ref-counted smart pointer for holding ref_counted objects. A nub::ref<T> is guaranteed to always point to a valid ref_counted object, and uses ref_counted's strong ref counts to achieve this. In order to provide this guarantee, it is possible that construction of a nub::ref<T> may throw an exception. For example, a nub::ref<T> cannot be constructed for a volatlie ref_counted object for which only weak references are available.

Member Function Documentation

template<class T>

void nub::ref< T >::reset

(

T *

p

)

[inline]

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>.

template<class T>

bool nub::ref< T >::operator<

(

const ref< T > &

other

)

const throw () [inline]

Comparison operator for sorting.

E.g. to allow insertion into std::map or std::set, etc.
