## com.sleepycat.persist.raw
Class RawStore

    java.lang.Object
      com.sleepycat.persist.raw.RawStore

    public class RawStore

extends Object

Provides access to the raw data in a store for use by general purpose tools. A `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:

1. An `EntityModel` may not be specified using `StoreConfig.setModel(com.sleepycat.persist.model.EntityModel)`. In other words, the configured model must be null (the default).
2. When storing entities, their format will not automatically be evolved to the current class definition, even if the current class definition has changed.
