>
> Give an outline item, I need to walk through all its children. ??The items at
> each level of the hierarchy form a linked list, chained together through
> their Prev and Next entries and accessed through the First and Last entries
> in the parent item?? so I created a simple patch to allow this kind of code:
> {code}
> if(node !=null){
> for (PDOutlineItem current : node.children()) {
> //do something with the
> }
> }
> {code}
> Given an item, PDOutlineNode.children returns an iterator that walks through
> the children until there is no NEXT or NEXT is equals to the starting element.
