public class ChainedParamReader
extends java.lang.Object

Description: In ParamReader class, user can not get inherited method parameter from the class they passed in. This is done because of performance. This class is intended to setup the inheritant chain. If the method could not be found in the derived class, it will try to search it from super class, if not in the immedidate super class it will search super class's super class, until it reaches the root which is java.lang.Object. This is not an eager load since it only start searching the super class when it is asked to User: pengyu Date: Sep 6, 2003 Time: 11:43:24 PM

If we still can not find the method we will return null. The returned array will have one name per parameter. The length of the array will be the same as the length of the Class[] array returned by Method.getParameterTypes().
