2. 3.x src/Mail/MailCacheInterface.php \Drupal\simplenews\Mail\MailCacheInterface::get()

Return a cached element, if existing.

Although group and key can be used to identify the requested cache, the implementations are responsible to create a unique cache key themself using the $mail. For example based on the node id and the language.

Parameters

\Drupal\simplenews\Mail\MailInterface $mail: The mail object.

string $group: Group of the cache key, which allows cache implementations to decide what they want to cache. Currently used groups:

• data: Raw data, e.g. attachments.
• build: Built and themed content, before personalizations like tokens.
• final: The final returned data. Caching this means that newsletter can not be personalized anymore.

string $key: Identifies the requested element, e.g. body or attachments.

Return value

mixed The cached data or NULL.
