1. 8.3 src/Asset/S3fsCssOptimizer.php \Drupal\s3fs\Asset\S3fsCssOptimizer::rewriteFileURI()

Prefixes all paths within a CSS file for processFile().

Note: the only reason this method is public is so color.module can call it; it is not on the AssetOptimizerInterface, so future refactorings can make it protected.

Parameters

array $matches: An array of matches by a preg_replace_callback() call that scans for url() references in CSS files, except for external or absolute ones.

Return value

string The file path.
