Interface CacheErrorHandler

All Known Implementing Classes:

SimpleCacheErrorHandler

public interface CacheErrorHandler

A strategy for handling cache-related errors. In most cases, any exception thrown by the provider should simply be thrown back at the client but, in some circumstances, the infrastructure may need to handle cache-provider exceptions in a different way.

Typically, failing to retrieve an object from the cache with a given id can be transparently managed as a cache miss by not throwing back such exception.
