public interface ConsistentErrorHandler extends ErrorHandler
MemcacheServiceException exceptions should be
handled by ErrorHandler.handleServiceError(MemcacheServiceException). This interface was
added to enable handling MemcacheServiceException thrown by the various MemcacheService.put(Object, Object) methods while preserving backward compatibility with ErrorHandler which did not handle such cases.| Modifier and Type | Method and Description |
|---|---|
void |
handleDeserializationError(InvalidValueException ivx)
Handles deserialization errors.

void |
handleServiceError(MemcacheServiceException ex)
Handles back-end service errors.

void handleDeserializationError(InvalidValueException ivx)
ErrorHandlerget methods, if the retrieved value
cannot be deserialized. This normally indicates an application upgrade
since the cache entry was stored, and should thus be treated as a cache
miss, which is the behavior of LogAndContinueErrorHandler (the
default).handleDeserializationError in interface ErrorHandlervoid handleServiceError(MemcacheServiceException ex)
ErrorHandlerMemcacheService methods in the event of a service error. This is
also called for MemcacheService.put(Object, Object) when the
combined key and value size is too large.
The handler may throw any RuntimeException, or it may simply
return for "permissive" error handling, which will generally emulate
behavior of a cache miss due to a discarded entry.
