Class MapProperty<K,V>
- 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
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:
public abstract class MapProperty<K,V> extends ReadOnlyMapProperty<K,V> implements Property<ObservableMap<K,V>>, WritableMapValue<K,V>
Property wrapping a ObservableMap. The value of a MapProperty can be get and set with ObservableObjectValue.get(), MapExpression.getValue(), WritableObjectValue.set(Object), and 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 bindBidirectional(Property) and unbindBidirectional(Property). The context of a MapProperty can be read with ReadOnlyProperty.getBean() and ReadOnlyProperty.getName().Since:

setValue
public void setValue(ObservableMap<K,V> v)
Set the wrapped value.Specified by:
setValuein interfaceWritableValue<ObservableMap<K,V>>Parameters:
v- The new value
-
bindBidirectional
public void bindBidirectional(Property<ObservableMap<K,V>> other)
Create a bidirectional binding between thisPropertyand another one. Bidirectional bindings exists independently of unidirectional bindings. So it is possible to add unidirectional binding to a property with bidirectional binding and vice-versa. However, this practice is discouraged.It is possible to have multiple bidirectional bindings of one Property.
JavaFX bidirectional binding implementation use weak listeners. This means bidirectional binding does not prevent properties from being garbage collected.
Specified by:
bindBidirectionalin interfaceProperty<ObservableMap<K,V>>Parameters:
other- the otherProperty
-
unbindBidirectional
public void unbindBidirectional(Property<ObservableMap<K,V>> other)
Remove a bidirectional binding between thisPropertyand another one. If no bidirectional binding between the properties exists, calling this method has no effect. It is possible to unbind by a call on the second property. This code will work:property1.bindBirectional(property2); property2.unbindBidirectional(property1);Specified by:
unbindBidirectionalin interfaceProperty<ObservableMap<K,V>>Parameters:
other- the otherProperty
-
toString
public String toString()
Returns a string representation of thisMapPropertyobject.Overrides:
toStringin classReadOnlyMapProperty<K,V>Returns:
a string representation of this
MapPropertyobject.
