- - ### Constructor Detail

    - #### ReadOnlyBooleanProperty

          public ReadOnlyBooleanProperty()

      The constructor of `ReadOnlyBooleanProperty`.

  - ### Method Detail

    - #### toString

          public String toString()

      Returns a string representation of this `ReadOnlyBooleanProperty` object.
      Overrides:
        `toString` in class `Object`
      Returns:
        a string representation of this `ReadOnlyBooleanProperty` object.

    - #### readOnlyBooleanProperty

          public static ReadOnlyBooleanProperty readOnlyBooleanProperty​(ReadOnlyProperty<Boolean> property)

      Returns a `ReadOnlyBooleanProperty` that wraps a `ReadOnlyProperty`. If the `ReadOnlyProperty` is already a `ReadOnlyBooleanProperty`, it will be returned. Otherwise a new `ReadOnlyBooleanProperty` is created that is bound to the `ReadOnlyProperty`. Note: null values will be interpreted as "false"
      Parameters:
        `property` - The source `ReadOnlyProperty`
      Returns:
        A `ReadOnlyBooleanProperty` that wraps the `ReadOnlyProperty` if necessary
      Throws:
        `NullPointerException` - if `property` is `null`
      Since:
        JavaFX 8.0

    - #### asObject

          public ReadOnlyObjectProperty<Boolean> asObject()

      Creates a `ReadOnlyObjectProperty` that holds the value of this `ReadOnlyBooleanProperty`. If the value of this `ReadOnlyBooleanProperty` changes, the value of the `ReadOnlyObjectProperty` will be updated automatically.
      Overrides:
        `asObject` in class `BooleanExpression`
      Returns:
        the new `ReadOnlyObjectProperty`
