Detailed Description

template<class ITERATOR>
class CxxUtils::releasing_iterator< ITERATOR >

Adapter to retrieve elements from a unique_ptr iterator via release().

This allows, say,

std::vector<std::unique_ptr<Foo> > c1 = ...;
std::vector<Foo*> c2;
c2.assign (releasing_iterator(c1.begin()), releasing_iterator(c1.end()));

All elements in c1 will be release'd.

Since this implies that a given iterator can only be dereferenced once, this iterator models input_iterator.
