- ## Method Details

  - ### 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
