Detailed Description

template<class T>
class CheckedIterator< T >

A range-checked iterator class for memory debugging.

A CheckedIterator<T> object exposes essentially the same interface as a T*, but stores a start/stop range that should bound the iterator. This range is checked with a call to ck_range() every time the iterator is derefenced, by either operator*() or operator->().

Constructor & Destructor Documentation

template<class T >

CheckedIterator< T >::CheckedIterator

(

)

[inline]

Default constructor.

This builds an iterator with an empty valid range, so a new value must be assigned to the iterator before it can be dereferenced. However, providing a default constructor helps keep source compatibility with non-debug iterators (i.e., raw pointers).
