protected static function ResourceResponseTestTrait::toCollectionResourceResponse in Drupal 8

Same name and namespace in other branches

1. 9 core/modules/jsonapi/tests/src/Functional/ResourceResponseTestTrait.php \Drupal\Tests\jsonapi\Functional\ResourceResponseTestTrait::toCollectionResourceResponse()
2. 10 core/modules/jsonapi/tests/src/Functional/ResourceResponseTestTrait.php \Drupal\Tests\jsonapi\Functional\ResourceResponseTestTrait::toCollectionResourceResponse()

Merges individual responses into a collection response.

Here, a collection response refers to a response with multiple resource objects. Not necessarily to a response to a collection route. In both cases, the document should indistinguishable.

Parameters

\Drupal\jsonapi\ResourceResponse[] $responses: An array or ResourceResponses to be merged.

string|null $self_link: The self link for the merged document if one should be set.

bool $is_multiple: Whether the responses are for a multiple cardinality field. This cannot be deduced from the number of responses, because a multiple cardinality field may have only one value.

Return value

\Drupal\jsonapi\ResourceResponse The merged ResourceResponse.
