BooleanPropertyBase (JavaFX 17)

Module javafx.base
Package javafx.beans.property

## Class BooleanPropertyBase

- java.lang.Object
- - javafx.beans.binding.BooleanExpression
  - - javafx.beans.property.ReadOnlyBooleanProperty
    - - javafx.beans.property.BooleanProperty
      - - javafx.beans.property.BooleanPropertyBase

- All Implemented Interfaces:
    `Observable`, `Property<Boolean>`, `ReadOnlyProperty<Boolean>`, `ObservableBooleanValue`, `ObservableValue<Boolean>`, `WritableBooleanValue`, `WritableValue<Boolean>`
  Direct Known Subclasses:
    `SimpleBooleanProperty`, `StyleableBooleanProperty`

      public abstract class BooleanPropertyBase
      extends BooleanProperty

  The class `BooleanPropertyBase` is the base class for a property wrapping a `boolean` 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

    `BooleanProperty`

- - ### Constructor Detail

    - #### BooleanPropertyBase

          public BooleanPropertyBase()

      The constructor of the `BooleanPropertyBase`.

    - #### BooleanPropertyBase

          public BooleanPropertyBase​(boolean initialValue)

      The constructor of the `BooleanPropertyBase`.
      Parameters:
        `initialValue` - the initial value of the wrapped value

  - ### Method Detail

    - #### 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 `WritableBooleanValue.set(boolean)` 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.

    - #### bind

          public void bind​(ObservableValue<? extends Boolean> rawObservable)

      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. Note:

      Parameters:
        `rawObservable` - The observable this `Property` should be bound to.

    - #### toString

          public String toString()

      Returns a string representation of this `BooleanPropertyBase` object.
      Overrides:
        `toString` in class `BooleanProperty`
      Returns:
        a string representation of this `BooleanPropertyBase` object.
