  • Method Details

    • addListener

      void addListener​(ListChangeListener<? super E> listener)
      Add a listener to this observable list.
      Parameters:
      listener - the listener for listening to the list changes

    • removeListener

      void removeListener​(ListChangeListener<? super E> listener)
      Tries to remove a listener from this observable list. If the listener is not attached to this list, nothing happens.
      Parameters:
      listener - a listener to remove

    • addAll

      boolean addAll​(E... elements)
      A convenience method for var-arg addition of elements.
      Parameters:
      elements - the elements to add
      Returns:
      true (as specified by Collection.add(E))

    • setAll

      boolean setAll​(E... elements)
      Clears the ObservableList and adds all the elements passed as var-args.
      Parameters:
      elements - the elements to set
      Returns:
      true (as specified by Collection.add(E))
      Throws:
      NullPointerException - if the specified arguments contain one or more null elements

    • setAll

      boolean setAll​(Collection<? extends E> col)
      Clears the ObservableList and adds all elements from the collection.
      Parameters:
      col - the collection with elements that will be added to this observableArrayList
      Returns:
      true (as specified by Collection.add(E))
      Throws:
      NullPointerException - if the specified collection contains one or more null elements

    • removeAll

      boolean removeAll​(E... elements)
      A convenience method for var-arg usage of the removeAll method.
      Parameters:
      elements - the elements to be removed
      Returns:
      true if list changed as a result of this call

    • retainAll

      boolean retainAll​(E... elements)
      A convenience method for var-arg usage of the retainAll method.
      Parameters:
      elements - the elements to be retained
      Returns:
      true if list changed as a result of this call

    • remove

      void remove​(int from, int to)
      A simplified way of calling sublist(from, to).clear(). As this is a common operation, ObservableList has this method for convenient usage.
      Parameters:
      from - the start of the range to remove (inclusive)
      to - the end of the range to remove (exclusive)
      Throws:
      IndexOutOfBoundsException - if an illegal range is provided

    • filtered

      default FilteredList<E> filtered​(Predicate<E> predicate)
      Creates a FilteredList wrapper of this list using the specified predicate.
      Parameters:
      predicate - the predicate to use
      Returns:
      new FilteredList
      Since:
      JavaFX 8.0

    • sorted

      default SortedList<E> sorted​(Comparator<E> comparator)
      Creates a SortedList wrapper of this list using the specified comparator.
      Parameters:
      comparator - the comparator to use or null for unordered List
      Returns:
      new SortedList
      Since:
      JavaFX 8.0

    • sorted

      default SortedList<E> sorted()
      Creates a SortedList wrapper of this list with the natural ordering.
      Returns:
      new SortedList
