Class MapProperty<K,V>

java.lang.Object

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

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

javafx.beans.property.MapProperty<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:: MapPropertyBase

public abstract class MapProperty<K,V>
extends ReadOnlyMapProperty<K,V>
implements Property<ObservableMap<K,V>>, WritableMapValue<K,V>

This class provides a full implementation of a Property wrapping an ObservableMap. The value of a MapProperty can be get and set with ObservableObjectValue.get(), ObservableValue.getValue(), WritableObjectValue.set(Object), and WritableValue.setValue(javafx.collections.ObservableMap). A property can be bound and unbound unidirectional with Property.bind(javafx.beans.value.ObservableValue) and Property.unbind(). Bidirectional bindings can be created and removed with Property.bindBidirectional(Property) and Property.unbindBidirectional(Property). The context of a MapProperty can be read with ReadOnlyProperty.getBean() and ReadOnlyProperty.getName().

Since:: JavaFX 2.1
