Class MapPropertyBase<K,​V>

Type Parameters:
K - the type of the key elements of the Map
V - the type of the value elements of the Map
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)

  • 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:
      toString in class MapProperty<K,​V>
      Returns:
      a string representation of this MapPropertyBase object.
