public function StockLevel::setValue in Commerce Stock 8

@inheritdoc

This updates the stock based on parameters set by the stock widget.

For computed fields we didn't find a chance to trigger the transaction, other than in ::setValue(). ::postSave() is not called for computed fields.

If you pass in a single value programmatically, note that we do not support the setting of a absolute stock levels here. We assume a stock adjustment if we get a singe value here. As usual a negative value decreases the stock level and a positive value increases the stock level.

Throws

\InvalidArgumentException In case of a invalid stock level value.
