public CacheTagsChecksumInterface::isValid($checksum, array $tags) Returns whether the checksum is valid for the given cache tags. Used when retrieving a cache item in a cache backend, to verify that no cache tag based invalidation happened. Parameters int $checksum: The checksum that was stored together with the cache item. string[] $tags: The cache tags that were stored together with the cache item. Return value bool FALSE if cache tag invalidations happened for the passed in tags since the

public CacheTagsChecksumInterface::getCurrentChecksum(array $tags) Returns the sum total of validations for a given set of tags. Called by a backend when storing a cache item.

Provides checksums for cache tag invalidations. Cache backends can use this to check if any cache tag invalidations happened for a stored cache item. To do so, they can inject the cache_tags.invalidator.checksum service, and when a cache item is written, store cache tags together with the current checksum, calculated by getCurrentChecksum(). When a cache item is fetched, the checksum can be validated with isValid(). The service will return FALSE if any of those cache tags were invalidated in th
