template<typename KeyType, typename ValueType, class HashFunctionType = DefaultHashFunctions, class TypeOfCriticalSectionToUse = DummyCriticalSection>
struct HashMap< KeyType, ValueType, HashFunctionType, TypeOfCriticalSectionToUse >::Iterator
Iterates over the items in a HashMap.
To use it, repeatedly call next() until it returns false, e.g.
HashMap <String, String> myMap;
while (i.next())
{
DBG (i.getKey() <<
" -> " << i.getValue());
}
#define DBG(textToWrite)
Writes a string to the standard error stream.

Iterates over the items in a HashMap.

The order in which items are iterated bears no resemblance to the order in which they were originally added!
Obviously as soon as you call any non-const methods on the original hash-map, any iterators that were created beforehand will cease to be valid, and should not be used.

Moves to the next item, if one is available.
When this returns true, you can get the item's key and value using getKey() and getValue(). If it returns false, the iteration has finished and you should stop.
