          public abstract Rectangle getNodeDimensions(Object value,
                                                      int row,
                                                      int depth,
                                                      boolean expanded,
                                                      Rectangle bounds)

      Returns, by reference in bounds, the size and x origin to place value at. The calling method is responsible for determining the Y location. If bounds is `null`, a newly created `Rectangle` should be returned, otherwise the value should be placed in bounds and returned.
      Parameters:
        `value` - the `value` to be represented
        `row` - row being queried
        `depth` - the depth of the row
        `expanded` - true if row is expanded, false otherwise
        `bounds` - a `Rectangle` containing the size needed to represent `value`
      Returns:
        a `Rectangle` containing the node dimensions, or `null` if node has no dimension
