Thomas Neidhart commented on COLLECTIONS-471:
---------------------------------------------
Committed patch with some additional changes in r1546220:
* added factory methods to be consistent with other decorators
* added corresponding methods boundedIterator in IteratorUtils
* remove unneeded variable firstNextCalled: pos can be used for this purpose
* changed logic of next and hasNext slightly: avoid calling iterator.hasNext
twice
* do not extends AbstractIteratorDecorator: makes code slightly more readable
by avoiding calling
super.hasNext and super.next and we need to implement all methods anyway
thus no real benefit of extending the decorator.
* javadoc updates
Thanks for this contribution!
If you have ideas for other useful iterators, feel free to create already
another ticket.
