public final class ReadOnlyJavaBeanLongProperty
extends ReadOnlyLongPropertyBase
implements ReadOnlyJavaBeanProperty<Number>

A ReadOnlyJavaBeanLongProperty provides an adapter between a regular read only Java Bean property of type long or Long and a JavaFX ReadOnlyLongProperty. It cannot be created directly, but a ReadOnlyJavaBeanLongPropertyBuilder has to be used.

As a minimum, the Java Bean class must implement a getter for the property. The class, as well as the getter method, must be declared public. If the getter of an instance of this class is called, the property of the Java Bean is returned. If the Java Bean property is bound (i.e. it supports PropertyChangeListeners), this ReadOnlyJavaBeanLongProperty will be aware of changes in the Java Bean. Otherwise it can be notified about changes by calling ReadOnlyJavaBeanProperty.fireValueChangedEvent().

Deploying an Application as a Module

If the Java Bean class is in a named module, then it must be reflectively accessible to the javafx.base module. A class is reflectively accessible if the module opens the containing package to at least the javafx.base module.

For example, if com.foo.MyBeanClass is in the foo.app module, the module-info.java might look like this:

module foo.app {
    opens com.foo to javafx.base;
}

Alternatively, a class is reflectively accessible if the module exports the containing package unconditionally.

Method Detail

get

public long get()

Returns the current value of this ObservableLongValue.

Specified by:

get in interface ObservableLongValue

Returns:

The current value

Throws:

UndeclaredThrowableException - if calling the getter of the Java Bean property throws an IllegalAccessException or an InvocationTargetException.
