public class ChainedParamReader
extends java.lang.Object

Description: In ParamReader class, user cannot get inherited method parameter from the class they passed in for performance reasons This class is walks up the inheritance chain. If the method is not found in the derived class, search in super class. If not found in the immedidate super class, search super class's super class, until the root, which is java.lang.Object, is reached. This is not an eager load since it only start searching the super class when it is asked to.
