IDataStorage

public class DatabaseStorage
extends java.lang.Object
implements IDataStorage

Created by Xiaofei on 16/3/24. An implementation of the interface IDataStorage. DatabaseStorage stores data in an instance of the DbCache class. It is thread-safe, which is guaranteed by the thread safety of DbCache. The functions within this class simply invoke the corresponding functions of the DbCache instance. They seldom check the correctness of arguments, which will be checked in the invocations of the corresponding functions. Programmers should use DataStorageFactory to obtain DatabaseStorage.
