Package org.drools.mvel.accessors

Class ClassFieldReader

java.lang.Object

org.drools.mvel.accessors.ClassFieldReader

All Implemented Interfaces:

Externalizable, Serializable, org.drools.core.base.AccessorKeySupplier, org.drools.core.base.FieldNameSupplier, org.drools.core.rule.accessor.ReadAccessor

public class ClassFieldReader
extends Object
implements Externalizable, org.drools.core.rule.accessor.ReadAccessor, org.drools.core.base.FieldNameSupplier, org.drools.core.base.AccessorKeySupplier

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.
