Class MapPropertyBase<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>
- Type Parameters:
-
K- the type of the key elements of theMap -
V- the type of the value elements of theMap
- 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>
- Direct Known Subclasses:
SimpleMapProperty
public abstract class MapPropertyBase<K,V>
extends MapProperty<K,V> The class
MapPropertyBase is the base class for a property wrapping an ObservableMap. It provides all the functionality required for a property except for the ReadOnlyProperty.getBean() and ReadOnlyProperty.getName() methods, which must be implemented by extending classes.- Since:
- JavaFX 2.1

Constructor Details
MapPropertyBase
public MapPropertyBase()
The Constructor of
MapPropertyBase
MapPropertyBase
public MapPropertyBase(ObservableMap<K,V> initialValue)
The constructor of the
MapPropertyBase.- Parameters:
-
initialValue- the initial value of the wrapped value
Method Details
fireValueChangedEvent
protected void fireValueChangedEvent()
Sends notifications to all attached
InvalidationListeners, ChangeListeners, and MapChangeListener. This method is called when the value is changed, either manually by calling WritableObjectValue.set(javafx.collections.ObservableMap) or in case of a bound property, if the binding becomes invalid.fireValueChangedEvent
protected void fireValueChangedEvent(MapChangeListener.Change<? extends K,? extends V> change)
Sends notifications to all attached
InvalidationListeners, ChangeListeners, and MapChangeListener. This method is called when the content of the list changes.- Parameters:
-
change- the change that needs to be propagated
invalidated
protected void invalidated()
The method
invalidated() can be overridden to receive invalidation notifications. This is the preferred option in Objects defining the property, because it requires less memory. The default implementation is empty.toString
public String toString()
Returns a string representation of this
MapPropertyBase object.- Overrides:
-
toStringin classMapProperty<K,V> - Returns:
- a string representation of this
MapPropertyBaseobject.
