Simple, fast java.util.Iterator for an array.

public final class ArrayIterator<T> implements SkippingIterator<T>, Iterable<T> {
  private final T[] array;
  private int position;
  private final int max;


Creates an ArrayIterator over an entire array.

array array to iterate over
  public ArrayIterator(T[] array) {
    if (array == null) {
      throw new IllegalArgumentException("array is null");
    this. = array// yeah, not going to copy the array here, for performance
    this. = 0;
