List<H>

Generic list

Operations

Code example:

function : Example() ~ Nil {
   # insert elements
   list := Collection.List->New()<FloatRef>;
   list->AddBack(33.3);
   list->AddFront(66.6);
   list->AddBack(99.9);

   # get size
   list->Size()->PrintLine();

   # get first and last item
   list->Front()->PrintLine();
   list->Back()->PrintLine();

   # iterate
   while(list->More()) {
      list->Get()->PrintLine();
      list->Next();
   };

   # iterate backward   
   backwards := list->BackwardIterator()<FloatRef>;
   while(backwards->More()) {
      backwards->Get()->PrintLine();
      backwards->Next();
   };
}
