Class ObjectStorageAdapterDB

  • All Implemented Interfaces:
    ObjectStorage
    public class ObjectStorageAdapterDB
extends java.lang.Object
implements ObjectStorage
    ObjectStorageAdapterDB provides an ObjectStorage implementation for use by Saveable objects. This allows Saveable objects to save or restore their state using a fixed set of primitives and primitive arrays. This implementation provides various data access methods for storing/retrieving data. In addition, support is provided for utilizing a Record object for data storage using a suitable schema.
