move

abstract fun move(from: Int, to: Int, count: Int)

Indicates that count children of current should be moved from index from to index to.

The to index is relative to the position before the change, so, for example, to move an element at position 1 to after the element at position 2, from should be 1 and to should be 3. If the elements were A B C D E, calling move(1, 3, 1) would result in the elements being reordered to A C B D E.
