public final class JavaBeanBooleanProperty
extends BooleanProperty
implements JavaBeanProperty<Boolean>
A JavaBeanBooleanProperty provides an adapter between a regular Java Bean property of type boolean or Boolean and a JavaFX BooleanProperty. It cannot be created directly, but a JavaBeanBooleanPropertyBuilder has to be used.

As a minimum, the Java Bean must implement a getter and a setter for the property. If the getter of an instance of this class is called, the property of the Java Bean is returned. If the setter is called, the value will be passed to the Java Bean property. If the Java Bean property is bound (i.e. it supports PropertyChangeListeners), this JavaBeanBooleanProperty will be aware of changes in the Java Bean. Otherwise it can be notified about changes by calling fireValueChangedEvent(). If the Java Bean property is also constrained (i.e. it supports VetoableChangeListeners), this JavaBeanBooleanProperty will reject changes, if it is bound to an ObservableValue<Boolean>.

Since:

JavaFX 2.1

  • Method Detail

    • get

      public boolean get()
      Get the wrapped value. Unlike WritableValue.getValue(), this method returns primitive boolean. Needs to be identical to WritableValue.getValue().

      Specified by:

      get in interface ObservableBooleanValue

      Specified by:

      get in interface WritableBooleanValue

      Returns:

      The current value

      Throws:

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

    • set

      public void set(boolean value)
      Set the wrapped value. Unlike WritableBooleanValue.setValue(java.lang.Boolean), this method uses primitive boolean.

      Specified by:

      set in interface WritableBooleanValue

      Parameters:

      value - The new value

      Throws:

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

    • bind

      public void bind(ObservableValue<? extends Boolean> observable)
      Create a unidirection binding for this Property.

      Note that JavaFX has all the bind calls implemented through weak listeners. This means the bound property can be garbage collected and stopped from being updated.

      Specified by:

      bind in interface Property<Boolean>

      Parameters:

      observable - The observable this Property should be bound to.

    • unbind

      public void unbind()
      Remove the unidirectional binding for this Property. If the Property is not bound, calling this method has no effect.

      Specified by:

      unbind in interface Property<Boolean>

      See Also:

      Property.bind(javafx.beans.value.ObservableValue)

    • isBound

      public boolean isBound()
      Can be used to check, if a Property is bound.

      Specified by:

      isBound in interface Property<Boolean>

      Returns:

      true if the Property is bound, false otherwise

      See Also:

      Property.bind(javafx.beans.value.ObservableValue)

    • 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<Boolean>

      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<Boolean>

      Returns:

      the name or an empty String

    • addListener

      public void addListener(ChangeListener<? super Boolean> listener)
      Adds a ChangeListener which will be notified whenever the value of the ObservableValue changes. If the same listener is added more than once, then it will be notified more than once. That is, no check is made to ensure uniqueness.

      Note that the same actual ChangeListener instance may be safely registered for different ObservableValues.

      The ObservableValue stores a strong reference to the listener which will prevent the listener from being garbage collected and may result in a memory leak. It is recommended to either unregister a listener by calling removeListener after use or to use an instance of WeakChangeListener avoid this situation.

      Specified by:

      addListener in interface ObservableValue<Boolean>

      Parameters:

      listener - The listener to register

      See Also:

      ObservableValue.removeListener(ChangeListener)

    • removeListener

      public void removeListener(ChangeListener<? super Boolean> listener)
      Removes the given listener from the list of listeners, that are notified whenever the value of the ObservableValue changes.

      If the given listener has not been previously registered (i.e. it was never added) then this method call is a no-op. If it had been previously added then it will be removed. If it had been added more than once, then only the first occurrence will be removed.

      Specified by:

      removeListener in interface ObservableValue<Boolean>

      Parameters:

      listener - The listener to remove

      See Also:

      ObservableValue.addListener(ChangeListener)

    • addListener

      public void addListener(InvalidationListener listener)
      Adds an InvalidationListener which will be notified whenever the Observable becomes invalid. If the same listener is added more than once, then it will be notified more than once. That is, no check is made to ensure uniqueness.

      Note that the same actual InvalidationListener instance may be safely registered for different Observables.

      The Observable stores a strong reference to the listener which will prevent the listener from being garbage collected and may result in a memory leak. It is recommended to either unregister a listener by calling removeListener after use or to use an instance of WeakInvalidationListener avoid this situation.

      Specified by:

      addListener in interface Observable

      Parameters:

      listener - The listener to register

      See Also:

      Observable.removeListener(InvalidationListener)

    • removeListener

      public void removeListener(InvalidationListener listener)
      Removes the given listener from the list of listeners, that are notified whenever the value of the Observable becomes invalid.

      If the given listener has not been previously registered (i.e. it was never added) then this method call is a no-op. If it had been previously added then it will be removed. If it had been added more than once, then only the first occurrence will be removed.

      Specified by:

      removeListener in interface Observable

      Parameters:

      listener - The listener to remove

      See Also:

      Observable.addListener(InvalidationListener)

    • fireValueChangedEvent

      public void fireValueChangedEvent()
      This method can be called to notify the adapter of a change of the Java Bean value, if the Java Bean property is not bound (i.e. it does not support PropertyChangeListeners).

      Specified by:

      fireValueChangedEvent in interface ReadOnlyJavaBeanProperty<Boolean>

    • 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<Boolean>

    • toString

      public String toString()
      Returns a string representation of this JavaBeanBooleanProperty object.

      Overrides:

      toString in class BooleanProperty

      Returns:

      a string representation of this JavaBeanBooleanProperty object.
