public CacheContextsManager::optimizeTokens(array $context_tokens) Optimizes cache context tokens (the minimal representative subset). A minimal representative subset means that any cache context token in the given set of cache context tokens that is a property of another cache context cache context token in the set, is removed. Hence a minimal representative subset is the most compact representation possible of a set of cache context tokens, that still captures the entire universe of variation
