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 Remove[T](position: Int, removed: Iterable[T]) extends Change[T]

Indicates a Removal in an ObservableBuffer.

Indicates a Removal in an ObservableBuffer.

Value Params
position

Position from where elements were removed

removed

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 Params
end

The end of the change interval.

permutation

Function that indicates the permutation that happened. The argument indicates the old index that contained the element prior to this change. Its return is the new index of the same element.

start

The start of the change interval.
