## Class ListProperty<E>

- java.lang.Object
- - javafx.beans.binding.ListExpression<E>
  - - javafx.beans.property.ReadOnlyListProperty<E>
    - - javafx.beans.property.ListProperty<E>

- Type Parameters:
    `E` - the type of the `List` elements
  All Implemented Interfaces:
    `Iterable<E>`, `Collection<E>`, `List<E>`, `Observable`, `Property<ObservableList<E>>`, `ReadOnlyProperty<ObservableList<E>>`, `ObservableListValue<E>`, `ObservableObjectValue<ObservableList<E>>`, `ObservableValue<ObservableList<E>>`, `WritableListValue<E>`, `WritableObjectValue<ObservableList<E>>`, `WritableValue<ObservableList<E>>`, `ObservableList<E>`
  Direct Known Subclasses:
    `ListPropertyBase`

      public abstract class ListProperty<E>
      extends ReadOnlyListProperty<E>
      implements Property<ObservableList<E>>, WritableListValue<E>

  This class provides a full implementation of a `Property` wrapping an `ObservableList`. The value of a `ListProperty` can be get and set with `ObservableObjectValue.get()`, `ListExpression.getValue()`, `WritableObjectValue.set(Object)`, and `setValue(ObservableList)`. A property can be bound and unbound unidirectional with `Property.bind(javafx.beans.value.ObservableValue)` and `Property.unbind()`. Bidirectional bindings can be created and removed with `bindBidirectional(Property)` and `unbindBidirectional(Property)`. The context of a `ListProperty` can be read with `ReadOnlyProperty.getBean()` and `ReadOnlyProperty.getName()`.
  Since:
    JavaFX 2.1

    - #### setValue

          public void setValue​(ObservableList<E> v)

      Set the wrapped value.
      Specified by:
        `setValue` in interface `WritableValue<E>`
      Parameters:
        `v` - The new value

    - #### bindBidirectional

          public void bindBidirectional​(Property<ObservableList<E>> other)

      Create a bidirectional binding between this `Property` and another one. Bidirectional bindings exists independently of unidirectional bindings. So it is possible to add unidirectional binding to a property with bidirectional binding and vice-versa. However, this practice is discouraged.

      It is possible to have multiple bidirectional bindings of one Property.

      JavaFX bidirectional binding implementation use weak listeners. This means bidirectional binding does not prevent properties from being garbage collected.

      Specified by:
        `bindBidirectional` in interface `Property<E>`
      Parameters:
        `other` - the other `Property`

    - #### unbindBidirectional

          public void unbindBidirectional​(Property<ObservableList<E>> other)

      Remove a bidirectional binding between this `Property` and another one. If no bidirectional binding between the properties exists, calling this method has no effect. It is possible to unbind by a call on the second property. This code will work:

      >          property1.bindBirectional(property2);
      >          property2.unbindBidirectional(property1);

      Specified by:
        `unbindBidirectional` in interface `Property<E>`
      Parameters:
        `other` - the other `Property`

    - #### toString

          public String toString()

      Returns a string representation of this `ListProperty` object.
      Overrides:
        `toString` in class `ReadOnlyListProperty<E>`
      Returns:
        a string representation of this `ListProperty` object.
