| class CPosLmItemIterator : public CBase |
Landmark item iterator.
This is an abstract base class for objects which iterates a set of database items in a single database.
A database item is an item which is stored in a landmark database, i.e. a landmark or a landmark category.
Note that an iterator either iterates categories or landmarks. The items are never mixed.
This class does not export a constructor. The instance is created by the operation which generates the item set to be iterated. The iterator may implement a caching scheme, but that scheme depends on what is iterated.

Fetches a sequence of database items from the iterated set.
The client supplies an ID array which will be filled by this operation. The array will be reset before any items are added.
The client specifies which database item sequence to fetch by supplying a start index (0 is the first item) and the number of items to fetch.

| TPosLmItemId | NextL | ( | ) | [pure virtual] |
Returns the next database item ID in the iterated set.
The first call will return the first database item ID in the set.
The next database item ID, or KPosLmNullItemId if there are no more database items in the iterated set.
| TUint | NumOfItemsL | ( | ) | [pure virtual] |
Returns the number of database items which are iterated.
Number of items in the iterated database item set.
| void | Reset | ( | ) | [pure virtual] |
Resets the database item iterator.
The next call to NextL will return the first database item ID in the iterated set.
