1. 9 core/modules/views/src/Plugin/views/sort/SortPluginBase.php \Drupal\views\Plugin\views\sort\SortPluginBase::getCacheContexts()

The cache contexts associated with this object.

These identify a specific variation/representation of the object.

Cache contexts are tokens: placeholders that are converted to cache keys by the @cache_contexts_manager service. The replacement value depends on the request context (the current URL, language, and so on). They're converted before storing an object in cache.

Return value

string[] An array of cache context tokens, used to generate a cache ID.
