- - ### Constructor Detail

    - #### ReadOnlyFloatProperty

          public ReadOnlyFloatProperty()

      The constructor of `ReadOnlyFloatProperty`.

  - ### Method Detail

    - #### toString

          public String toString()

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

    - #### readOnlyFloatProperty

          public static <T extends Number> ReadOnlyFloatProperty readOnlyFloatProperty​(ReadOnlyProperty<T> property)

      Returns a `ReadOnlyFloatProperty` that wraps a `ReadOnlyProperty`. If the `ReadOnlyProperty` is already a `ReadOnlyFloatProperty`, it will be returned. Otherwise a new `ReadOnlyFloatProperty` is created that is bound to the `ReadOnlyProperty`. Note: null values will be interpreted as 0f
      Type Parameters:
        `T` - The type of Number to be wrapped
      Parameters:
        `property` - The source `ReadOnlyProperty`
      Returns:
        A `ReadOnlyFloatProperty` that wraps the `ReadOnlyProperty` if necessary
      Throws:
        `NullPointerException` - if `property` is `null`
      Since:
        JavaFX 8.0

    - #### asObject

          public ReadOnlyObjectProperty<Float> asObject()

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