All Implemented Interfaces:

NumberExpression ， Observable ， Property<Number> ， ReadOnlyProperty<Number> ， ObservableLongValue ， ObservableNumberValue ， ObservableValue<Number> ， WritableLongValue ， WritableNumberValue ， WritableValue<Number>

public class ReadOnlyLongWrapper
extends SimpleLongProperty

该类提供了一个方便的类来定义只读属性。 它创建两个同步的属性。 一个属性是只读的，可以传递给外部用户。 另一个属性是可读写的，只能在内部使用。

从以下版本开始：

JavaFX 2.0

构造方法详细信息

ReadOnlyLongWrapper

public ReadOnlyLongWrapper()

构造函数为 ReadOnlyLongWrapper

ReadOnlyLongWrapper

public ReadOnlyLongWrapper(long initialValue)

构造函数 ReadOnlyLongWrapper

参数

initialValue - 包装值的初始值

ReadOnlyLongWrapper

public ReadOnlyLongWrapper(Object bean,
                           String name)

构造函数为 ReadOnlyLongWrapper

参数

bean - 这个 ReadOnlyLongProperty的豆

name - 这个 ReadOnlyLongProperty的名字

ReadOnlyLongWrapper

public ReadOnlyLongWrapper(Object bean,
                           String name,
                           long initialValue)

构造函数为 ReadOnlyLongWrapper

参数

bean - 这个 ReadOnlyLongProperty的豆

name - 这个 ReadOnlyLongProperty的名字

initialValue - 包装值的初始值

方法详细信息

getReadOnlyProperty

public ReadOnlyLongProperty getReadOnlyProperty()

返回readonly属性，该属性与此 ReadOnlyLongWrapper同步。

结果

只读属性

fireValueChangedEvent

protected void fireValueChangedEvent()

发送所有附件的通知InvalidationListeners和ChangeListeners 。 通过调用LongPropertyBase.set(long)手动或绑定属性的情况下，如果绑定变为无效，则调用此方法。

重写：

fireValueChangedEvent在 LongPropertyBase
