Class ReadOnlyMapWrapperEx<K,V>

java.lang.Object

javafx.beans.binding.MapExpression<K,V>

javafx.beans.property.ReadOnlyMapProperty<K,V>

javafx.beans.property.MapProperty<K,V>

javafx.beans.property.MapPropertyBase<K,V>

javafx.beans.property.SimpleMapProperty<K,V>

javafx.beans.property.ReadOnlyMapWrapper<K,V>

org.eclipse.gef.common.beans.property.ReadOnlyMapWrapperEx<K,V>

Type Parameters:

K - The key type of the wrapped ObservableMap.

V - The value type of the wrapped ObservableMap.

All Implemented Interfaces:

Map<K,V>, Observable, Property<ObservableMap<K,V>>, ReadOnlyProperty<ObservableMap<K,V>>, ObservableMapValue<K,V>, ObservableObjectValue<ObservableMap<K,V>>, ObservableValue<ObservableMap<K,V>>, WritableMapValue<K,V>, WritableObjectValue<ObservableMap<K,V>>, WritableValue<ObservableMap<K,V>>, ObservableMap<K,V>

public class ReadOnlyMapWrapperEx<K,V>
extends ReadOnlyMapWrapper<K,V>

A replacement for ReadOnlyMapWrapper to fix the following JavaFX issues:

• All listeners were removed when removing one (https://bugs.openjdk.java.net/browse/JDK-8136465): fixed by keeping track of all listeners and ensuring that remaining listeners are re-added when a listener is removed.
• Change notifications are fired even when the observed value did not change.(https://bugs.openjdk.java.net/browse/JDK-8089169)
• Bidirectional binding not working (https://bugs.openjdk.java.net/browse/JDK-8089557): fixed by not forwarding listeners to the nested read-only property but rather keeping the lists of listeners distinct.
