public interface ConstMapIterator

An iterator for a map. The iterator points to a map entry when it's created so next() shouldn't be called at the start of the iteration.

Here's an example on how to iterate over a map: for (ConstIterator iterator = map.constIterator(); iterator.atEntry(); iterator.next()) { Object key = iterator.getKey(); Object value = iterator.getValue(); ... }
