public static function ResourceIdentifier::isDuplicate in JSON:API 8.2

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.
