    • Method Detail

      • hasNext

        public boolean hasNext()
        Specified by:
        hasNext in interface java.util.Iterator<java.lang.Long>

      • nextLong

        public long nextLong()
        Specified by:
        nextLong in interface java.util.PrimitiveIterator.OfLong

      • fetchNext

        protected abstract boolean fetchNext()
        Fetches the next item in this iterator. Returns whether or not a next item was found. If a next item was found, that value must have been set inside the implementation of this method using next(long).

      • next

        protected boolean next​(long nextItem)
        Called from inside an implementation of fetchNext() if a next item was found. This method returns true so that it can be used in short-hand conditionals (TODO what are they called?), like: 
         protected boolean fetchNext()
 {
     return source.hasNext() ? next( source.next() ) : false;
 }
        Parameters:
        nextItem - the next item found.
