Class LongPropertyBase

javafx.beans.property.LongPropertyBase

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

Direct Known Subclasses:: SimpleLongProperty, StyleableLongProperty

public abstract class LongPropertyBase
extends LongProperty

The class LongPropertyBase is the base class for a property wrapping a long 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:: LongProperty

Constructor Details

LongPropertyBase

public LongPropertyBase()

The constructor of the LongPropertyBase.

LongPropertyBase

public LongPropertyBase(long initialValue)

The constructor of the LongPropertyBase.

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 WritableLongValue.set(long) 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 LongPropertyBase object.

Overrides:: toString in class LongProperty
Returns:: a string representation of this LongPropertyBase object.
