Schnittstelle CacheBacking

Alle bekannten Implementierungsklassen:
AbstractCacheBacking, AbstractFileCacheBacking, AbstractIndexedFileCacheBacking, AsynchronousFileCacheBacking, DefaultFileCacheBacking, FlatFileCacheBacking, ZippedFileCacheBacking
public interface CacheBacking
Interface for the backing to the cache; usually a file, but could be an in-memory backing for testing.

aspectj and jvmti provide no suitable guarantees on locking for class redefinitions, so every implementation must have a some locking mechanism to prevent invalid reads.
