function CacheCollector::set

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(). If you are writing data to somewhere in addition to the cache item in ::set(), you should call static::updateCache() at the end of your ::set implementation. This avoids a race condition if another request starts with an empty cache before your ::set() call. For example: Drupal\Core\State\State.
