public function IsMobileCacheContext::getCacheableMetadata in Mobile Detect 8.2
Gets the cacheability metadata for the context.
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.
Return value
\Drupal\Core\Cache\CacheableMetadata A cacheable metadata object.
