Package org.drools.mvel.accessors

Class ClassFieldReader

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