 Please subclass to provide your own iterator for the the ResourceCollection,
 note <code>iterator()</code> is implemented to call <code>open()</code>
 and track the results in for later <code>purge()</code>.

 As an example if the iterator was working off a File then
 the inputstream should be closed.

 Subclass must call super.close( close ) to allow the list
