php SplFixedArray 不再是 Iterator 而是 InteratorAggregate

Question

现在 SplFixedArray 不是 Interator，而是 IteratorAggregate，我如何更改以下代码以适用于 PHP 8

声明(strict_types=1);

命名空间 BitWasp\Bitcoin\Transaction\Mutator;

抽象类 AbstractCollectionMutator 实现 \Iterator、\ArrayAccess、\Countable { /** * @var \SplFixedArray */ 受保护的$集；

/**
 * @return array
 */
public function all(): array
{
    return $this->set->toArray();
}

/**
 * @return bool
 */
public function isNull(): bool
{
    return count($this->set) === 0;
}

/**
 * @return int
 */
public function count(): int
{
    return $this->set->count();
}

/**
 *
 */
public function rewind()
{
    $this->set->rewind();
}

/**
 * @return mixed
 */
public function current()
{
    return $this->set->current();
}

/**
 * @return int
 */
public function key()
{
    return $this->set->key();
}

/**
 *
 */
public function next()
{
    $this->set->next();
}

/**
 * @return bool
 */
public function valid()
{
    return $this->set->valid();
}

/**
 * @param int $offset
 * @return bool
 */
public function offsetExists($offset)
{
    return $this->set->offsetExists($offset);
}

/**
 * @param int $offset
 */
public function offsetUnset($offset)
{
    if (!$this->offsetExists($offset)) {
        throw new \InvalidArgumentException('Offset does not exist');
    }

    $this->set->offsetUnset($offset);
}

/**
 * @param int $offset
 * @return mixed
 */
public function offsetGet($offset)
{
    if (!$this->set->offsetExists($offset)) {
        throw new \OutOfRangeException('Nothing found at this offset');
    }
    return $this->set->offsetGet($offset);
}

/**
 * @param int $offset
 * @param mixed $value
 */
public function offsetSet($offset, $value)
{
    $this->set->offsetSet($offset, $value);
}

}

我尝试将 Implements \Iterator 更改为 \InteratorAggregate 但它无法正常工作。
