WCTransactionalEmailPostsManager::maybe_prime_mapping_option_caches │ private │ WC 1.0

Prime the option caches for all known email type mappings in one query.

With lazy post creation most mappings don't exist, and without priming each lookup of a missing mapping costs one SELECT on sites without a persistent object cache. Runs once per request.

Method of the class: WCTransactionalEmailPostsManager{}

No Hooks.

Returns

null. Nothing (null).

Usage

// private - for code of main (parent) class only
$result = $this->maybe_prime_mapping_option_caches(): void;
