Thanks Keith!, That definately makes sense. Bob. -----Original Message----- From: Keith Visco [mailto:[EMAIL PROTECTED]] Sent: Tuesday, September 04, 2001 4:11 PM To: [EMAIL PROTECTED] Subject: Re: [castor-dev] what type of class members generate "has<varname>()" methods? Robert, has-methods are generated for primitive types. Since you cannot have a null primitive type, there is no way to determine if the value was set explicitly or is simply the default value. Since there is often the need to check whether or not a value was set explicitly, we introduced the has-methods. Hope that helps your understanding... --Keith Robert Ollila wrote: > > Hi, > > Can anyone tell me under what circumstances the XML source generator creates > the "has<varname>()" method for a particular class member variable.
