| class TDblQueIterBase |
A base class that provides implementation for the doubly linked list iterator.
It also encapsulates a pointer to the current link list element.
The class is abstract and is not intended to be instantiated.

| IMPORT_C | TDblQueIterBase | ( | TDblQueBase & | aQue | ) | [protected] |
Constructs the iterator for the specified doubly linked list.
| TDblQueBase & aQue | A reference to a doubly linked list header. |
| IMPORT_C TAny * | DoCurrent | ( | ) | [protected] |
Gets the current item in the queue.
The function is an implementation for TDblQueIter::operator T*().
TDblQueIter::operator T*
| IMPORT_C TAny * | DoPostDec | ( | ) | [protected] |
Gets the current item and then moves to the previous item.
The function is an implementation for TDblQueIter::operator--().
| IMPORT_C TAny * | DoPostInc | ( | ) | [protected] |
Gets the current item and then moves to the next item.
The function is an implementation for TDblQueIter::operator++().
| IMPORT_C void | DoSet | ( | TAny * | aLink | ) | [protected] |
Sets the iterator to point to a specific element in the list.
The function is an implementation for TDblQueIter::Set().
| TAny * aLink | A pointer to the current list element. |
| IMPORT_C void | SetToFirst | ( | ) |
Sets the iterator to point to the first element in the doubly linked list.
The function can be called to re-set the pointer at any time during the iterator's existence.
The function can be called even if the list has no elements.
| IMPORT_C void | SetToLast | ( | ) |
Sets the iterator to point to the last element in the doubly linked list. The function can be called to re-set the pointer at any time during the iterator's existence.
The function can be called even if the list has no elements.
| TInt | iOffset | [protected] |
The offset of a component link object within elements that form the list.
