Details
__construct(LanguageManagerInterface $language_manager)
Constructs a new LanguagesCacheContext service.
static string
getLabel()
Returns the label of the cache context.
string
getContext($type = NULL)
Returns the string representation of the cache context.
A cache context service's name is used as a token (placeholder) cache key, and is then replaced with the string returned by this method.
CacheableMetadata
getCacheableMetadata($type = NULL)
Gets the cacheability metadata for the context based on the parameter value.
There are three valid cases for the returned CacheableMetadata object:
- An empty object means this can be optimized away safely.
- A max-age of 0 means that this context can never be optimized away. It will never bubble up and cache tags will not be used.
- Any non-zero max-age and cache tags will bubble up into the cache item if this is optimized away to allow for invalidation if the context value changes.
