public class ReflectionBasedReferenceTypeDelegate
extends Object
implements ReferenceTypeDelegate

Author:

colyer A delegate for a resolved type that uses runtime type information (java.lang.reflect) to answer questions. This class uses only Java 1.4 features to answer questions. In a Java 1.5 environment use the Java5ReflectionBasedReferenceTypeDelegate subtype.
