org.drools.base
Class ClassFieldExtractor

java.lang.Object
  org.drools.base.ClassFieldExtractor

All Implemented Interfaces:

java.io.Serializable, Extractor, FieldExtractor

public class ClassFieldExtractor
extends java.lang.Object
implements FieldExtractor

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.
