Class OneMemberEnumeration

java.lang.Object
  |
  +--net.walend.ejb.OneMemberEnumeration

All Implemented Interfaces:

java.util.Enumeration

public class OneMemberEnumeration

extends java.lang.Object

implements java.util.Enumeration

An Enumeration that contains a single object. This class exists because findBy methods have to return either an Enumeration or the exact entity bean interface. You'd think that'd work out OK, but it doesn't.

I had to use this hack to return abstract types from within the EJB 1.1 specification without hacking client code.
