Package org.drools.mvel.accessors

Class ClassFieldReader

java.lang.Object
org.drools.mvel.accessors.ClassFieldReader
All Implemented Interfaces:
Externalizable, Serializable, org.drools.base.base.AccessorKeySupplier, org.drools.base.rule.accessor.ReadAccessor, FieldNameSupplier
public class ClassFieldReader extends Object implements Externalizable, org.drools.base.rule.accessor.ReadAccessor, FieldNameSupplier, org.drools.base.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.
