javafx.beans.property

Class MapProperty<K,V>

java.lang.Object

<any>

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:

Property<<any>>, ReadOnlyProperty<<any>>

Direct Known Subclasses:

MapPropertyBase

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

This class provides a full implementation of a Property wrapping an javafx.collections.ObservableMap. The value of a MapProperty can be get and set with #get(), #getValue(), #set(Object), and #setValue(javafx.collections.ObservableMap). A property can be bound and unbound unidirectional with #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:

JavaFX 2.1

Method Detail

setValue

public void setValue(<any> v)

bindBidirectional

public void bindBidirectional(Property<<any>> other)

Create a bidirectional binding between this Property and 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:

bindBidirectional in interface Property<<any>>

Parameters:

other - the other Property

unbindBidirectional

public void unbindBidirectional(Property<<any>> other)

Remove a bidirectional binding between this Property and 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:

unbindBidirectional in interface Property<<any>>

Parameters:

other - the other Property

toString

public java.lang.String toString()

Returns a string representation of this MapProperty object.

Overrides:

toString in class ReadOnlyMapProperty<K,V>

Returns:

a string representation of this MapProperty object.
