ClassFieldReader (Drools :: Core 6.3.0.Beta1 API)

java.lang.Object
- org.drools.core.base.ClassFieldReader

All Implemented Interfaces:

Externalizable, Serializable, InternalReadAccessor, ReadAccessor
```
public class ClassFieldReader
extends Object
implements Externalizable, InternalReadAccessor
```
This provides access to fields, and what their numerical index/object type is. This is basically a wrapper class around dynamically generated subclasses of BaseClassFieldExtractor, which allows serialization by regenerating the accessor classes when needed.
