Doubly linked non-constant list iterator The List class above only provides for the list framework. This is one of two classes which allow list iteration, insertion, and removal. This class can be used to modify a list. Unlike ConstListIter, this class can insert and remove elements from a list as well as look at or observe a list. ConstListIter should be used whenever the list is not modified. More...

Doubly linked non-constant list iterator The List class above only provides for the list framework. This is one of two classes which allow list iteration, insertion, and removal. This class can be used to modify a list. Unlike ConstListIter, this class can insert and remove elements from a list as well as look at or observe a list. ConstListIter should be used whenever the list is not modified.
All of the operations take place to the right of a conceptual cursor. The cursor starts out before the first element of the list and can be incremented past the last element of the list. Going further than the end of the list results in an exception. All additions and deletions occur to the right of this conceptual cursor. In addition, this class uses the Notice class to ensure that multiple iterators which are observing the same list are updated as the list changes. This is important when multiple iterators are used.
The output from this example would look like:
89 89 21 21 2 2 2 17 2 17 one: len=5 pos=2 21 17 2 12 18 two: len=5 pos=4 21 17 2 12 18 three: len=5 pos=0 21 17 2 12 18
Tip: This class uses the "Notice" classes to implement "dynamic" cursors so that multiple cursors are updated as elements are added and removed from the list;

void casacore::ListIter< t >::removeRight | ( | ) |
This function removes the element to the right of the current cursor position.
|
virtual |
This function swaps the list section after the current position of the list with the right section of the list of another iterator.
This can be particularly useful for "remembering" the position of a cursor in a list.
