Constructor and Description
AtomicChange(ObservableMap<K,V> source, K key, V removedValue, V addedValue) Creates a new MapListenerHelperEx.AtomicChange that represents a change comprising a single elementary sub-change.
AtomicChange(ObservableMap<K,V> source, MapChangeListener.Change<? extends K,? extends V> change) Creates a new MapListenerHelperEx.AtomicChange for the passed in source, based on the data provided in the passed-in change.

Constructor Detail

AtomicChange

public AtomicChange(ObservableMap<K,V> source,
                    K key,
                    V removedValue,
                    V addedValue)

Creates a new MapListenerHelperEx.AtomicChange that represents a change comprising a single elementary sub-change.

Parameters:

source - The source ObservableMap from which the change originated.

key - The key to which the change is related.

removedValue - The value that was removed by this change or null if no value was removed.

addedValue - The value that was added by this change or null if no value was added.

AtomicChange

public AtomicChange(ObservableMap<K,V> source,
                    MapChangeListener.Change<? extends K,? extends V> change)

Creates a new MapListenerHelperEx.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 wrapped ObservableMap with themselves as source.

Parameters:

source - The new source ObservableMap.

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.
