  - ### getNodeDimensions

    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
