  - ### toString

    public String toString()
    Returns a string representation of this `ReadOnlyIntegerProperty` object.
    Overrides:
      `toString` in class `Object`
    Returns:
      a string representation of this `ReadOnlyIntegerProperty` object.

  - ### readOnlyIntegerProperty

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

  - ### asObject

    public ReadOnlyObjectProperty<Integer> asObject()
    Creates a `ReadOnlyObjectProperty` that holds the value of this `ReadOnlyIntegerProperty`. If the value of this `ReadOnlyIntegerProperty` changes, the value of the `ReadOnlyObjectProperty` will be updated automatically.
    Overrides:
      `asObject` in class `IntegerExpression`
    Returns:
      the new `ReadOnlyObjectProperty`
