  - ### Method Detail

    - #### getTreeTableView

          public TreeTableView<S> getTreeTableView()

      Returns the TableView upon which this event occurred.
      Returns:
        The TableView control upon which this event occurred.

    - #### getTableColumn

          public TreeTableColumn<S,​T> getTableColumn()

      Returns the TreeTableColumn upon which this event occurred.
      Returns:
        The TreeTableColumn that the edit occurred in.

    - #### getTreeTablePosition

          public TreeTablePosition<S,​T> getTreeTablePosition()

      Returns the position upon which this event occurred.
      Returns:
        The position upon which this event occurred.

    - #### getNewValue

          public T getNewValue()

      Returns the new value input by the end user. This is not the value to go back into the TableView.items list - this new value represents just the input for a single cell, so it is likely that it needs to go back into a property within an item in the TableView.items list.
      Returns:
        An Object representing the new value input by the user.

    - #### getOldValue

          public T getOldValue()

      Attempts to return the old value at the position referred to in the TablePosition returned by `getTreeTablePosition()`. This may return null for a number of reasons.
      Returns:
        Returns the value stored in the position being edited, or null if it can not be retrieved.

    - #### getRowValue

          public TreeItem<S> getRowValue()

      Convenience method that returns the value for the row (that is, from the TableView `items` list), for the row contained within the `TablePosition` returned in `getTreeTablePosition()`.
      Returns:
        the row value
