    简介

    /* 常量 */
    public const int MIT_NEED_ANY;
    public const int MIT_NEED_ALL;
    public const int MIT_KEYS_NUMERIC;

    预定义常量

    MultipleIterator::MIT_NEED_ANY

    Do not require all sub iterators to be valid in iteration.

    MultipleIterator::MIT_NEED_ALL

    Require all sub iterators to be valid in iteration.

    MultipleIterator::MIT_KEYS_NUMERIC

    Keys are created from the sub iterators position.

    MultipleIterator::MIT_KEYS_ASSOC

    Keys are created from sub iterators associated information.
