Question

I have a class which uses a HashSet and I want the class implement Iterable, I do not, however, want the class iterator to support the remove() method.

The default iterator of HashSet is HashSet.KeyIterator which is a private class within the HashSet class, so I cannot simply extend it and override the remove method.

Ideally I would like to avoid writing a wrapper class for KeyIterator, but I am at a loss as to how else I could easily and simply implement my own iterator in any other way.

Any ideas?

Cheers,

Pete

java.util.Collections.unmodifiableSet(myHashSet).iterator();
