DataUtils::line_refund_history_matches_quantities │ private │ WC 1.0

Whether every prior refund line for a product matches its quantity-derived amount.

True means the difference between the line's refunded total and the sum of unit-price amounts is pure rounding drift, so the final-chunk top-up in {@see compute_quantity_refund_total()} can safely reconcile it. Gross values are compared as formatted decimals at currency precision — never raw float equality. A refund line with no units (qty 0, the dollar-only form) is off-schedule by definition.

Usage

// private - for code of main (parent) class only
$result = $this->line_refund_history_matches_quantities( $item, $line_refunds ): bool;
$item(WC_Order_Item_Product) (required)
The original order line.
$line_refunds(array) (required)
Prior refund lines as list<array{qty: int, gross: float}> (positive magnitudes).
