represents a change comprising a single elementary sub-change.source
- The source ObservableSet
from which the change
originated.removedElement
- The element that was removed by this change or
null
if no value was removed.addedElement
- The element that was added by this change or

if no value was added.public AtomicChange(ObservableSet<E> source, SetChangeListener.Change<? extends E> change)
SetListenerHelperEx.AtomicChange
for the passed
in source, based on the data provided in the passed-in change.
This is basically used to allow properties wrapping an
ObservableSet
to re-fire change events of their wrapped
ObservableSet
with themselves as source.
source
- The new source ObservableSet
.change
- The change to infer a new change from. It is expected that
the change is in initial state. In either case it will be
reset to initial state.public E getElementAdded()
