AtomicChange
public AtomicChange(javafx.collections.ObservableMap<K, V> source, K key, V removedValue, V addedValue) Creates a newMapListenerHelperEx.AtomicChange
that represents a change comprising a single elementary sub-change.- Parameters:
source
- The sourceObservableMap
from which the change originated.key
- The key to which the change is related.removedValue
- The value that was removed by this change ornull
if no value was removed.addedValue
- The value that was added by this change ornull
if no value was added.

AtomicChange
public AtomicChange(javafx.collections.ObservableMap<K, V> source, javafx.collections.MapChangeListener.Change<? extends K, ? extends V> change) Creates a newMapListenerHelperEx.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
ObservableMap
to re-fire change events of their wrappedObservableMap
with themselves as source.- Parameters:
source
- The new sourceObservableMap
.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.
