Interface ICacheEntryProcessor<TK, TV, TArg, TRes>
An invocable function that allows applications to perform compound operations on a cache entry atomically, according the defined consistency of a cache.
Any cache entry mutations will not take effect until after the Process(IMutableCacheEntry<TK, TV>, TArg) method has completedS execution.
If an exception is thrown by an entry processor, a Caching Implementation must wrap any exception thrown wrapped in an CacheEntryProcessorException If this occurs no mutations will be made to the cache entry.
