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.
Overrides CacheableDependencyInterface::getCacheContexts
