Namespace

Code

protected function constructValue($data, $context) {
    // Just like \Drupal\serialization\Normalizer\FieldItemNormalizer's logic
    // for denormalization, which uses TypedDataInterface::setValue(), allow the
    // keying by main property name ("value") to be implied.
    if (!is_array($data)) {
        $data = [
            'value' => $data,
        ];
    }

        '👍',
        '👎',
    ], TRUE)) {
        throw new \UnexpectedValueException('Only 👍 and 👎 are acceptable values.');
    }
    $data['value'] = $data['value'] === '👍';
