For Apex developers, the CacheManager class has several methods that can be used to cache data in 1 of the 3 supported cache types - transaction, organization platform cache, and session platform cache. Each cache type implements the interface CacheManager.Cacheable - regardless of which cache type you choose, the way you interact with each cache type is consistent.
// This will cache a Map<String, Group> that contains all queues in the current org (if the data has not been cached) // or it will return the cached version of the data (if the data has previously been cached) public static Map<String, Group> getQueues() { String cacheKey = 'queues'; Map<String, Group> queueDeveloperNameToQueueGroup; if (CacheManager.getOrganization().contains(cacheKey)) { queueDeveloperNameToQueueGroup = (Map<String, Group>) CacheManager.getOrganization().get(cacheKey); } else { queueDeveloperNameToQueueGroup = new Map<String, Group>(); for (Group queueGroup : [SELECT Id, DeveloperName, Email, Name FROM Group WHERE Type = 'Queue']) { queueDeveloperNameToQueueGroup.put(queueGroup.DeveloperName, queueGroup); } CacheManager.getOrganization().put(cacheKey, queueDeveloperNameToQueueGroup); } return queueDeveloperNameToQueueGroup; }
