Examples of ItemIterator

org.dspace.content.ItemIterator
Specialized iterator for DSpace Items. This iterator is used for loading items into memory one by one, since in many cases, it would not make sense to load a set of items into memory all at once. For example, loading in an entire community or site's worth of items wouldn't make sense. Note that this class is not a real Iterator, as it does not implement the Iterator interface @author Robert Tansley @author Richard Jones @version $Revision: 3761 $
org.openhab.binding.astro.internal.util.ItemIterator
Iterates through all astro items. @author Gerhard Riegler @since 1.6.0
