sealed trait Change[T]

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 subclasses are exclusive to each other. This enables using pattern matching:

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 subclasses 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.

case class Reorder[T](start: Int, end: Int, permutation: Int => Int) extends Change[T]

Indicates a Reordering in an ObservableBuffer.

Indicates a Reordering in an ObservableBuffer.

Value parameters

end

Revert the order in the ObservableBuffer. Fires only '''one''' change notification on the list.

''Implementation note'': This method uses `reverse` method from `javafx.collections.FXCollections`. It is not called reverse to not confuse with method with same name from scala.collection.mutable.Buffer

Value parameters

buffer

Buffer to be reverted.
