  • Method Detail

    • bindContentBidirectional

      public void bindContentBidirectional​(ObservableMap<K,​V> map)
      Creates a bidirectional content binding of the ObservableMap, that is wrapped in this ReadOnlyMapProperty, and another ObservableMap.

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

      Parameters:
      map - the ObservableMap this property should be bound to
      Throws:
      NullPointerException - if map is null
      IllegalArgumentException - if map is the same map that this ReadOnlyMapProperty points to

    • unbindContentBidirectional

      public void unbindContentBidirectional​(Object object)
      Deletes a bidirectional content binding between the ObservableMap, that is wrapped in this ReadOnlyMapProperty, 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 map that this ReadOnlyMapProperty points to

    • bindContent

      public void bindContent​(ObservableMap<K,​V> map)
      Creates a content binding between the ObservableMap, that is wrapped in this ReadOnlyMapProperty, and another ObservableMap.

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

      Parameters:
      map - the ObservableMap this property should be bound to
      Throws:
      NullPointerException - if map is null
      IllegalArgumentException - if map is the same map that this ReadOnlyMapProperty points to

    • unbindContent

      public void unbindContent​(Object object)
      Deletes a content binding between the ObservableMap, that is wrapped in this ReadOnlyMapProperty, 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 map that this ReadOnlyMapProperty points to

    • equals

      public boolean equals​(Object obj)
      Specified by:
      equals in interface Map<K,​V>
      Overrides:
      equals in class Object

    • hashCode

      public int hashCode()
      Returns a hash code for this ReadOnlyMapProperty object.
      Specified by:
      hashCode in interface Map<K,​V>
      Overrides:
      hashCode in class Object
      Returns:
      a hash code for this ReadOnlyMapProperty object.

    • toString

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