Constructor Detail

### AbstractDocument.ElementEdit

    public AbstractDocument.ElementEdit(Element e,
                                        int index,
                                        Element[] removed,
                                        Element[] added)

  Constructs an edit record. This does not modify the element so it can safely be used to catch up a view to the current model state for views that just attached to a model.

Parameters:
  `e` - the element
  `index` - the index into the model >= 0
  `removed` - a set of elements that were removed
  `added` - a set of elements that were added
