      Constructor Description
      IntIntervalSequenceIterator​(int[] left, int[] len)
      Creates a new interval-sequence iterator by specifying arrays of left extremes and lengths.
      IntIntervalSequenceIterator​(int[] left, int[] len, int n)
      Creates a new interval-sequence iterator by specifying arrays of left extremes and lengths, and the number of valid entries.

      • IntIntervalSequenceIterator

        public IntIntervalSequenceIterator​(int[] left,
                                           int[] len)
        Creates a new interval-sequence iterator by specifying arrays of left extremes and lengths. Note that the two arrays are not copied, so they are supposed not to be changed during the iteration.
        Parameters:
        left - an array containing the left extremes of the intervals generating this iterator.
        len - an array (of the same length as left) containing the number of integers (greater than zero) in each interval.

                                           int[] len,
                                           int n)
        Creates a new interval-sequence iterator by specifying arrays of left extremes and lengths, and the number of valid entries. Note that the two arrays are not copied, so they are supposed not to be changed during the iteration.
        Parameters:
        left - an array containing the left extremes of the intervals generating this iterator.
        len - an array (of the same length as left) containing the number of integers (greater than zero) in each interval.
        n - the number of valid entries in left and len.

      • nextInt

        public int nextInt()
        Description copied from interface: LazyIntIterator
        The next integer returned by this iterator, or the special marker if this iterator is exhausted.
        Specified by:
        nextInt in interface LazyIntIterator
        Returns:
        next integer returned by this iterator, or the special marker if this iterator is exhausted.
      • skip

        public int skip​(int n)
        Description copied from interface: LazyIntIterator
        Skips a given number of elements.
        Specified by:
        skip in interface LazyIntIterator
        Parameters:
        n - the number of elements to skip.
        Returns:
        the number of elements actually skipped (which might be less than n if this iterator is exhausted).
