BlockContentUuidLookup
class BlockContentUuidLookup extends CacheCollector (View source)
| internal |
A cache collector that caches IDs for block_content UUIDs.
As block_content entities are used as block plugin derivatives, it is a fairly safe limitation that there are not hundreds of them, a site will likely run into problems with too many block content entities in other places than a cache that only stores UUID's and IDs. The same assumption is not true for other content entities.

Methods
Constructs a BlockContentUuidLookup instance.
Implements \Drupal\Core\Cache\CacheCollectorInterface::set().
Flags an offset value to be written to the persistent cache.
Resolves a cache miss.
Writes a value to the persistent cache immediately.
Normalizes a cache ID in order to comply with database limitations.
Details
__construct(CacheBackendInterface $cache, LockBackendInterface $lock, EntityTypeManagerInterface $entity_type_manager)
Constructs a BlockContentUuidLookup instance.
protected string
getCid()
Gets the cache ID.
has(string $key)
Returns whether data exists for this key.
mixed
get(string $key)
Gets value from the cache.
set(string $key, mixed $value)
Implements \Drupal\Core\Cache\CacheCollectorInterface::set().
This is not persisted by default. In practice this means that setting a value will only apply while the object is in scope and will not be written back to the persistent cache. This follows a similar pattern to static vs. persistent caching in procedural code. Extending classes may wish to alter this behavior, for example by adding a call to persist().
delete(string $key)
Deletes the element.
It depends on the specific case and implementation whether this has a permanent effect or if it just affects the current request.
protected
persist(string $key, bool $persist = TRUE)
Flags an offset value to be written to the persistent cache.
protected mixed
resolveCacheMiss(string $key)
Resolves a cache miss.
When an offset is not found in the object, this is treated as a cache miss. This method allows classes using this implementation to look up the actual value and allow it to be cached.
protected
updateCache(bool $lock = TRUE)
Writes a value to the persistent cache immediately.
protected string
normalizeLockName(string $cid)
Normalizes a cache ID in order to comply with database limitations.
reset()
Resets the local cache.
Does not clear the persistent cache.
clear()
Clears the collected cache entry.
destruct()
Performs destruct operations.
protected
lazyLoadCache()
Loads the cache if not already done.
protected
invalidateCache()
Invalidate the cache.
