Class ReadOnlyJavaBeanIntegerProperty

  • All Implemented Interfaces:
    NumberExpression, Observable, ReadOnlyJavaBeanProperty<Number>, ReadOnlyProperty<Number>, ObservableIntegerValue, ObservableNumberValue, ObservableValue<Number>
    public final class ReadOnlyJavaBeanIntegerProperty
extends ReadOnlyIntegerPropertyBase
implements ReadOnlyJavaBeanProperty<Number>
    A ReadOnlyJavaBeanIntegerProperty provides an adapter between a regular read only Java Bean property of type int or Integer and a JavaFX ReadOnlyIntegerProperty. It cannot be created directly, but a ReadOnlyJavaBeanIntegerPropertyBuilder 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 ReadOnlyJavaBeanIntegerProperty will be aware of changes in the Java Bean. Otherwise it can be notified about changes by calling 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 int get()
        Returns the current value of this ObservableIntegerValue.
        Specified by:
        get in interface ObservableIntegerValue
        Returns:
        The current value
        Throws:
        UndeclaredThrowableException - if calling the getter of the Java Bean property throws an IllegalAccessException or an InvocationTargetException.

      • getBean

        public Object getBean()
        Returns the Object that contains this property. If this property is not contained in an Object, null is returned.
        Specified by:
        getBean in interface ReadOnlyProperty<Number>
        Returns:
        the containing Object or null

      • getName

        public String getName()
        Returns the name of this property. If the property does not have a name, this method returns an empty String.
        Specified by:
        getName in interface ReadOnlyProperty<Number>
        Returns:
        the name or an empty String

      • dispose

        public void dispose()
        Signals to the JavaFX property that it will not be used anymore and any references can be removed. A call of this method usually results in the property stopping to observe the Java Bean property by unregistering its listener(s).
        Specified by:
        dispose in interface ReadOnlyJavaBeanProperty<Number>
