Description copied from interface: ResultCache

Calling this method instructs the cache to return null to all ResultCache.get(K) calls and ignore any ResultCache.put(K, T) calls from the current thread until the cache is cleared. Context: after a write operation on a connection (which is assumed to be handled exclusively by a dedicated thread), the local cache must be cleared and the global cache bypassed until the connection is returned.

bypassForCurrentThread in interface ResultCache<Integer,T>
