  • Type Parameters:
    E - the type parameter of this list
    F - the upper bound of the type of the source list
    All Implemented Interfaces:
    Iterable<E>, Collection<E>, List<E>, Observable, ObservableList<E>
    Direct Known Subclasses:
    FilteredList, SortedList 
    public abstract class TransformationList<E,​F>
extends ObservableListBase<E>
implements ObservableList<E>
    A base class for all lists that wrap another list in a way that changes (transforms) the wrapped list's elements, order, size, or structure. If the source list is observable, a listener is automatically added to it and the events are delegated to sourceChanged(javafx.collections.ListChangeListener.Change)
    Since:
    JavaFX 8.0

  • Constructor Detail

    • TransformationList

      protected TransformationList​(ObservableList<? extends F> source)
      Creates a new Transformation list wrapped around the source list.
      Parameters:
      source - the wrapped list

  • Method Detail

    • getSource

      public final ObservableList<? extends F> getSource()
      The source list specified in the constructor of this transformation list.
      Returns:
      The List that is directly wrapped by this TransformationList

    • isInTransformationChain

      public final boolean isInTransformationChain​(ObservableList<?> list)
      Checks whether the provided list is in the chain under this TransformationList. This means the list is either the direct source as returned by getSource() or the direct source is a TransformationList, and the list is in it's transformation chain.
      Parameters:
      list - the list to check
      Returns:
      true if the list is in the transformation chain as specified above.

    • sourceChanged

      protected abstract void sourceChanged​(ListChangeListener.Change<? extends F> c)
      Called when a change from the source is triggered.
      Parameters:
      c - the change

    • getSourceIndex

      public abstract int getSourceIndex​(int index)
      Maps the index of this list's element to an index in the direct source list.
      Parameters:
      index - the index in this list
      Returns:
      the index of the element's origin in the source list
      See Also:
      getSource()

    • getSourceIndexFor

      public final int getSourceIndexFor​(ObservableList<?> list,
                                   int index)
      Maps the index of this list's element to an index of the provided list. The list must be in the transformation chain.
      Parameters:
      list - a list from the transformation chain
      index - the index of an element in this list
      Returns:
      the index of the element's origin in the provided list
      See Also:
      isInTransformationChain(javafx.collections.ObservableList)

    • getViewIndex

      public abstract int getViewIndex​(int index)
      Maps the index of the direct source list's element to an index in this list.
      Parameters:
      index - the index in the source list
      Returns:
      the index of the element in this list if it is contained in this list or negative value otherwise
      Since:
