    public ReadOnlyListProperty()
    The constructor of `ReadOnlyListProperty`.

- ## Method Details

  - ### bindContentBidirectional

    public void bindContentBidirectional(ObservableList<E> list)
    Creates a bidirectional content binding of the `ObservableList`, that is wrapped in this `ReadOnlyListProperty`, and another `ObservableList`.

    A bidirectional content binding ensures that the content of two `ObservableLists` is the same. If the content of one of the lists changes, the other one will be updated automatically.

    Parameters:
      `list` - the `ObservableList` this property should be bound to
    Throws:
      `NullPointerException` - if `list` is `null`
      `IllegalArgumentException` - if `list` is the same list that this `ReadOnlyListProperty` points to

  - ### unbindContentBidirectional

    public void unbindContentBidirectional(Object object)
    Deletes a bidirectional content binding between the `ObservableList`, that is wrapped in this `ReadOnlyListProperty`, and another `Object`.
    Parameters:
      `object` - the `Object` to which the bidirectional binding should be removed
    Throws:
      `NullPointerException` - if `object` is `null`
      `IllegalArgumentException` - if `object` is the same list that this `ReadOnlyListProperty` points to

  - ### bindContent

    public void bindContent(ObservableList<E> list)
    Creates a content binding between the `ObservableList`, that is wrapped in this `ReadOnlyListProperty`, and another `ObservableList`.

    A content binding ensures that the content of the wrapped `ObservableLists` is the same as that of the other list. If the content of the other list changes, the wrapped list will be updated automatically. Once the wrapped list is bound to another list, you must not change it directly.

    Parameters:
      `list` - the `ObservableList` this property should be bound to
    Throws:
      `NullPointerException` - if `list` is `null`
      `IllegalArgumentException` - if `list` is the same list that this `ReadOnlyListProperty` points to

  - ### unbindContent

    public void unbindContent(Object object)
    Deletes a content binding between the `ObservableList`, that is wrapped in this `ReadOnlyListProperty`, and another `Object`.
    Parameters:
      `object` - the `Object` to which the binding should be removed
    Throws:
      `NullPointerException` - if `object` is `null`
      `IllegalArgumentException` - if `object` is the same list that this `ReadOnlyListProperty` points to

  - ### equals

    public boolean equals(Object obj)
    Specified by:
      `equals` in interface `Collection<E>`
    Specified by:
      `equals` in interface `List<E>`
    Overrides:
      `equals` in class `Object`

  - ### hashCode

    public int hashCode()
    Specified by:
      `hashCode` in interface `Collection<E>`
    Specified by:
      `hashCode` in interface `List<E>`
    Overrides:
      `hashCode` in class `Object`

  - ### toString

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