public class RawStore
extends java.lang.Object
RawStore provides access to stored entities without using
entity classes or key classes. Keys are represented as simple type objects
or, for composite keys, as RawObject instances, and entities are
represented as RawObject instances.
RawStore objects are thread-safe. Multiple threads may safely
call the methods of a shared RawStore object.
When using a RawStore, the current persistent class definitions
are not used. Instead, the previously stored metadata and class definitions
are used. This has several implications:
EntityModel may not be specified using StoreConfig.setModel(com.sleepycat.persist.model.EntityModel). In other words, the configured model must be
null (the default).| Constructor and Description |

WARNING: To guard against memory leaks, the application should discard all references to the closed handle. While BDB makes an effort to discard references from closed objects to the allocated memory for an environment, this behavior is not guaranteed. The safe course of action for an application is to discard all references to closed BDB objects.
