protected function Shipping::applyHighest in Commerce Shipping 8.2

Applies the highest tax rate found on the order.

If an order has one order item taxed using the standard rate (e.g. 20%) and one taxed using the intermediate rate (e.g. 15%), then the standard rate will be applied, just like with applyDefault().

However, if the order only has an order item taxed using the intermediate rate, then the intermediate rate will be applied.

Parameters

\Drupal\commerce_order\Entity\OrderInterface $order: The order.

\Drupal\commerce_order\Adjustment[] $tax_adjustments: The tax adjustments.
