Class ClassFieldAccessorFactory

java.lang.Object
  org.drools.core.base.ClassFieldAccessorFactory

public class ClassFieldAccessorFactory
extends Object

This generates subclasses of BaseClassFieldExtractor to provide field extractors. This should not be used directly, but via ClassFieldExtractor (which ensures that it is all nicely serializable).
