File

Class

NormalizerBase

Base normalizer used in all JSON:API normalizers.

Namespace

Drupal\jsonapi\Normalizer

Code

protected function checkFormat($format = NULL) {
  // The parent implementation allows format-specific normalizers to be used
  // for normalization without a format. The JSON:API module wants to be
  // cautious. Hence it only allows its normalizers to be used for the
  // JSON:API format, to avoid JSON:API-specific normalizations showing up in
  // the REST API.
  return $format === $this->format;
}
