The Cache namespace contains methods for managing
the platform cache.
The following are the classes in the Cache namespace.
CacheBuilder Interface
An interface for safely retrieving and removing values from a session or org cache. Use the interface to generate a value that you want to store in the cache. The interface checks for cache misses, which means you no longer need to check for null cache values yourself.
Org Class
Use the Cache.Org class to add, retrieve, and manage values in the org cache. Unlike the session cache, the org cache is not tied to any session and is available to the organization across requests and to all users.
OrgPartition Class
Contains methods to manage cache values in the org cache of a specific partition. Unlike the session cache, the org cache is not tied to any session. It’s available to the organization across requests and to all users.
Partition Class
Base class of Cache.OrgPartition and Cache.SessionPartition. Use the subclasses to manage the cache partition for org caches and session caches.
Session Class
Use the Cache.Session class to add, retrieve, and manage values in the session cache. The session cache is active as long as the user’s Salesforce session is valid (the user is logged in, and the session is not expired).
SessionPartition Class
Contains methods to manage cache values in the session cache of a specific partition.
Cache Exceptions
The Cache namespace contains exception classes.
Visibility Enum
Use the Cache.Visibility enumeration in the Cache.Session or Cache.Org methods to indicate whether a cached value is visible only in the value’s namespace or in all namespaces.
