- 11.x core/modules/jsonapi/src/JsonApiResource/ResourceIdentifier.php \Drupal\jsonapi\JsonApiResource\ResourceIdentifier::isDuplicate()
Determines if two ResourceIdentifiers are the same.
This method does not consider parallel relationships with different arity values to be duplicates. For that, use the isParallel() method.
Parameters
\Drupal\jsonapi\JsonApiResource\ResourceIdentifier $a: The first ResourceIdentifier object.
\Drupal\jsonapi\JsonApiResource\ResourceIdentifier $b: The second ResourceIdentifier object.
Return value
bool TRUE if both relationships reference the same resource and do not have two distinct arity's, FALSE otherwise.
For example, if $a and $b both reference the same resource identifier, they can only be distinct if they *both* have an arity and those values are not the same. If $a or $b does not have an arity, they will be considered duplicates.
