Interface LazyIntIterator


public interface LazyIntIterator
A lazy iterator over the integers.

An instance of this class represent a (skippable) iterator over the integers. The iterator is exhausted when an implementation-dependent special marker is returned. This fully lazy architecture halves the number of method calls w.r.t. Java's eager iterators.

  • Method Summary

    Modifier and Type Method Description
    int nextInt()
    The next integer returned by this iterator, or the special marker if this iterator is exhausted.
    int skip​(int n)
    Skips a given number of elements.
  • Method Details

    • nextInt

      int nextInt()
      The next integer returned by this iterator, or the special marker if this iterator is exhausted.
      Returns:
      next integer returned by this iterator, or the special marker if this iterator is exhausted.
    • skip

      int skip​(int n)
      Skips a given number of elements.
      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).
