Interface CacheImplementationInterface

All Superinterfaces:

Map

All Known Implementing Classes:

LRUHashtable, OSCacheImplementation

public interface CacheImplementationInterface

extends Map

Classes which can be used as a cache implementation need to implement this interface. An implementation of this interface has to be thread-safe to guarantee correctness.
