public SimplePermutationChange(int from,
 int to,
 int[] permutation,
 ObservableList<E> list)

Method Details

getRemoved

public List<E> getRemoved()

Description copied from class: ListChangeListener.Change

An immutable list of removed/replaced elements. If no elements were removed from the list, an empty list is returned.

Specified by:

getRemoved in class ListChangeListener.Change<E>

Returns:

a list with all the removed elements

getPermutation

protected int[] getPermutation()

Description copied from class: ListChangeListener.Change

If this change is an permutation, it returns an integer array that describes the permutation. This array maps directly from the previous indexes to the new ones. This method is not publicly accessible and therefore can return an array safely. The 0 index of the array corresponds to index ListChangeListener.Change.getFrom() of the list. The same applies for the last index and ListChangeListener.Change.getTo(). The method is used by ListChangeListener.Change.wasPermutated() and ListChangeListener.Change.getPermutation(int) methods.

Overrides:

getPermutation in class NonIterableChange<E>

Returns:

empty array if this is not permutation or an integer array containing the permutation
