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.
