public interface Property<T>
extends ReadOnlyProperty<T>, WritableValue<T>
Generic interface that defines the methods common to all (writable) properties independent of their type.

  • Method Details

    • bind

      void bind​(ObservableValue<? extends T> observable)
      Create a unidirection binding for this Property.

      Note that JavaFX has all the bind calls implemented through weak listeners. This means the bound property can be garbage collected and stopped from being updated.

      observable - The observable this Property should be bound to.
      NullPointerException - if observable is null
    • unbind

      void unbind()
      Remove the unidirectional binding for this Property. If the Property is not bound, calling this method has no effect.
      See Also:
    • isBound

      boolean isBound()
      Can be used to check, if a Property is bound.
      true if the Property is bound, false otherwise
      See Also:
    • bindBidirectional

      void bindBidirectional​(Property<T> 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.

      other - the other Property
      NullPointerException - if other is null
      IllegalArgumentException - if other is this
    • unbindBidirectional

      void unbindBidirectional​(Property<T> 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:
      other - the other Property
      NullPointerException - if other is null
      IllegalArgumentException - if other is this
