Direct Known Subclasses:

IQRegister, IQSearchRequest, SearchResult

public abstract class HashExtension

extends XMLData

implements Extension

A HashExtension holds the code which is shared by several other extensions, including the register extension and part of the search extension implementation. NOTE: it is my personal hope that this general type of extension dies a horrible death at a later date, probably at the hand of XML forms. all parameters are subject to interpretation - the names are meant to be labels to editable text boxes, with instructions being broadcast on how to use the interface. also note that the values do not have default states - is represented by name.equals(""), whereas name=null indicates the element is not present
