Class DoublePropertyBase

javafx.beans.property.DoublePropertyBase

All Implemented Interfaces:: NumberExpression, Observable, Property<Number>, ReadOnlyProperty<Number>, ObservableDoubleValue, ObservableNumberValue, ObservableValue<Number>, WritableDoubleValue, WritableNumberValue, WritableValue<Number>

Direct Known Subclasses:: SimpleDoubleProperty, StyleableDoubleProperty

public abstract class DoublePropertyBase
extends DoubleProperty

The class DoublePropertyBase is the base class for a property wrapping a double value. 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 2.0
See Also:: DoubleProperty

Constructor Details

DoublePropertyBase

public DoublePropertyBase()

The constructor of the DoublePropertyBase.

DoublePropertyBase

public DoublePropertyBase(double initialValue)

The constructor of the DoublePropertyBase.

Parameters:: initialValue - the initial value of the wrapped value

Method Details

fireValueChangedEvent

protected void fireValueChangedEvent()

Sends notifications to all attached InvalidationListeners and ChangeListeners. This method is called when the value is changed, either manually by calling WritableDoubleValue.set(double) or in case of a bound property, if the binding becomes invalid.

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 DoublePropertyBase object.

Overrides:: toString in class DoubleProperty
Returns:: a string representation of this DoublePropertyBase object.
