Trait that indicates a Change in an ObservableBuffer.
Trait that indicates a Change in an ObservableBuffer. It is a simpler version of JavaFX's
ListChangeListener.Change,
where each subclass indicates a specific change operation.
Unlike JavaFX, all subcalsses are exclusive to each other. This enables using pattern matching:
items.onChange((_, changes) => { for (change <- changes) change match { case Add(pos, added) => ... case Remove(pos, removed) => ... case Reorder(from, to, permutation) => ... case Update(pos, updated) => ... } })
"replace" is represented as two changes Remove and Add.
