Package org.drools.mvel.accessors

Class ClassFieldAccessor

java.lang.Object

org.drools.mvel.accessors.ClassFieldAccessor

All Implemented Interfaces:

Externalizable, Serializable, org.drools.core.base.FieldAccessor, org.drools.core.spi.AcceptsReadAccessor, org.drools.core.spi.ReadAccessor, org.drools.core.spi.WriteAccessor

public class ClassFieldAccessor
extends Object
implements org.drools.core.spi.AcceptsReadAccessor, org.drools.core.base.FieldAccessor, 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.
