- 9 core/modules/layout_builder/src/Cache/LayoutBuilderIsActiveCacheContext.php \Drupal\layout_builder\Cache\LayoutBuilderIsActiveCacheContext::getCacheableMetadata()
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.
Parameters
string|null $parameter: The parameter, or NULL to indicate all possible parameter values.
Return value
\Drupal\Core\Cache\CacheableMetadata A cacheable metadata object.
Throws
\LogicException Thrown if the passed in parameter is invalid.
