It looks like you don't actually want input order, but rather the order
in which preferences are expressed, i.e. chronological order. Some data
models allow you to have timestamps associated with preferences.

When input-data have [1,101,3 / 1,105,2 / 1,103,5 / 1,104,1 / 1,102,4],
I want to get item-list which order-list is written like [101, 105, 103,
104, 102].
I can not get a result because getItemIDs() of DataModel return the
FastIDSet.
I am trying to consider a preference of [Item 105] when I evaluate a
preference of [Item 103]

Define "previous item"?
Data points have no ordering in the framework.
It sounds like something you will have to track yourself.

I want to know previous item when estimate preference for item.
