## Method Details

### 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
