Detailed Description

KisTileDataStoreIterator, KisTileDataStoreReverseIterator, KisTileDataStoreClockIterator

• are general iterators for the contents of KisTileDataStore. The store starts holding a lock when returns one of such iterators, so no one will be able to change the list while you are iterating.

But be careful! You can't change the list while iterating either, because it can invalidate the iterator. This is a general rule.
