    • LongIntervalSequenceIterator

      public LongIntervalSequenceIterator(long[] left, long[] 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.

    • LongIntervalSequenceIterator

      public LongIntervalSequenceIterator(long[] left, long[] 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.

    • nextLong

      public long nextLong()
      Description copied from interface: LazyLongIterator
      The next long returned by this iterator, or the special marker if this iterator is exhausted.
      Specified by:
      nextLong in interface LazyLongIterator
      Returns:
      next long returned by this iterator, or the special marker if this iterator is exhausted.

    • skip

      public long skip(long n)
      Description copied from interface: LazyLongIterator
      Skips a given number of elements.
      Specified by:
      skip in interface LazyLongIterator
      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).
