DoublePropertyBase (Java SE 10 & JDK 10 )

java.lang.Object
- javafx.beans.binding.NumberExpressionBase
- - javafx.beans.binding.DoubleExpression
  - - javafx.beans.property.ReadOnlyDoubleProperty
    - - javafx.beans.property.DoubleProperty
      - 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

- Constructor Detail
  - 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 Detail
  - 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.
