java.lang.Object
- org.drools.mvel.accessors.ClassFieldAccessor

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, org.drools.base.base.FieldAccessor, org.drools.base.rule.accessor.AcceptsReadAccessor, org.drools.base.rule.accessor.ReadAccessor, org.drools.base.rule.accessor.WriteAccessor
```
public class ClassFieldAccessor
extends java.lang.Object
implements org.drools.base.rule.accessor.AcceptsReadAccessor, org.drools.base.base.FieldAccessor, java.io.Externalizable
```
This is a wrapper for a ClassFieldExtractor that provides default values and a simpler interface for non-used parameters like the working memory, when the field extractor is used outside the working memory scope.
