Method paddedPartition

output/java_guava/1.4.16/Iterators.java:604–606

Divides an iterator into unmodifiable sublists of the given size, padding the final iterator with null values if necessary. For example, partitioning an iterator containing [a, b, c, d, e] with a partition size of 3 yields [[a, b, c], [d, e, null]] -- an outer iterator containing two

(Iterator<T> iterator, int size)

    return partitionImpl(iterator, size, true);
  }
