Public Functions Documentation🔗
function IteratorBase🔗
IteratorBase(
const IteratorBase< false > & iter
)
construct a const_iterator from an iterator
Parameters:
- iter is the iterator which will deliver list and index info for the const_iterator
function operator=🔗
IteratorBase & operator=(
const IteratorBase< false > & rhs
)
assigns a const_iterator from an iterator; needs to be implemented because the copy c'tor is also explicitly implemented
Parameters:
- rhs is the iterator which will deliver list and index info for the const_iterator
Return: reference to this iterator object
function operator++🔗
IteratorBase & operator++()
prefix increment iterator, so it points to the next list element when trying to increment beyond the end of the list, iterator stays pointing at the end
Return: reference to this iterator object
function operator--🔗
IteratorBase & operator--()
prefix decrement iterator, so it points to the previous list element decrementing an iterator pointing already towards begin() has no effect (iterator stays at begin())
Return: reference to this iterator object
function operator==🔗
template <bool IsConstIteratorOther>
bool operator==(
const IteratorBase< IsConstIteratorOther > & rhs
) const
comparing list iterators for equality the referenced list position is compared, not the content of the list element (T-typed) -> there is no content for fictional elements at BEGIN_END_LINK_INDEX only iterators of the same parent list can be compared; in case of misuse, terminate() is invoked
Parameters:
- rhs is the 2nd iterator to compare to
Return: list position for two iterators is the same (true) or different (false)
function operator!=🔗
template <bool IsConstIteratorOther>
bool operator!=(
const IteratorBase< IsConstIteratorOther > & rhs
) const
comparing list iterators for non-equality the referenced list position is compared, not the content of the list element (T-typed) -> there is no content for fictional elements at BEGIN_END_LINK_INDEX only iterators of the same parent list can be compared; in case of misuse, terminate() is invoked
Parameters:
- rhs is the 2nd iterator to compare to
Return: list position for two iterators is the same (true) or different (false)
function operator*🔗
reference operator*() const
dereferencing element content via iterator-position element
Return: reference to list element data
function operator->🔗
pointer operator->() const
dereferencing element content via iterator-position element
Return: pointer to const list data element
