    Set the wrapped value.

    Parameters:

    v - The new value

  • bindBidirectional

    public void bindBidirectional(Property<Number> 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<Number>

    Parameters:

    other - the other Property

  • unbindBidirectional

    public void unbindBidirectional(Property<Number> 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<Number>

    Parameters:

    other - the other Property

  • toString

    public String toString()

    Returns a string representation of this IntegerProperty object.

    Overrides:

    toString in class ReadOnlyIntegerProperty

    Returns:

    a string representation of this IntegerProperty object.

  • integerProperty

    public static IntegerProperty integerProperty(Property<Integer> property)

    Returns a IntegerProperty that wraps a Property and is bidirectionally bound to it. Changing this property will result in a change of the original property.

    This is very useful when bidirectionally binding an ObjectProperty and a IntegerProperty.

    IntegerProperty integerProperty = new SimpleIntegerProperty(1);
       ObjectProperty<Integer> objectProperty = new SimpleObjectProperty<>(2);
    
       // Need to keep the reference as bidirectional binding uses weak references
       IntegerProperty objectAsInteger = IntegerProperty.integerProperty(objectProperty);
    
       integerProperty.bindBidirectional(objectAsInteger);

    Another approach is to convert the IntegerProperty to ObjectProperty using asObject() method.

    Note: null values in the source property will be interpreted as 0

    Parameters:

    property - The source Property

    Returns:

    A IntegerProperty that wraps the Property

    Throws:

    NullPointerException - if property is null

    Since:

    JavaFX 8.0

  • asObject

    public ObjectProperty<Integer> asObject()

    Creates an ObjectProperty that bidirectionally bound to this IntegerProperty. If the value of this IntegerProperty changes, the value of the ObjectProperty will be updated automatically and vice-versa.

    Can be used for binding an ObjectProperty to IntegerProperty.

    IntegerProperty integerProperty = new SimpleIntegerProperty(1);
       ObjectProperty<Integer> objectProperty = new SimpleObjectProperty<>(2);
    
       objectProperty.bind(integerProperty.asObject());

    Overrides:

    asObject in class ReadOnlyIntegerProperty

    Returns:

    the new ObjectProperty
