Cache Exceptions

The Cache namespace contains exception classes.

All exception classes support built-in methods for returning the error message and exception type. See Exception Class and Built-In Exceptions in the Force.com Apex Code Developer’s Guide.

The Cache namespace contains these exceptions.

Exception Thrown when
Cache.Session.SessionCacheException An error occurred while adding or retrieving a value in the session cache.
Cache.Session.SessionCacheNoSessionException An attempt is made to access the cache when the session cache isn’t available.
Cache.OrgCacheException An attempt is made to access a partition that doesn’t exist or whose name is invalid.
Cache.InvalidParamException An invalid parameter value is passed into a method of Cache.Session or Cache.Org. This occurs when:
  • The key referenced is null or empty or is not alphanumeric.
  • The namespace referenced is null or empty.
  • The partition name is null or empty or is not alphanumeric.
  • Another referenced value is null.
Cache.PlatformCacheInvalidOperationException A cache put or remove call is made that is not allowed. For example, when calling put or remove inside a Visualforce constructor.
