hi all i've committed patch providing this functionality into the HEAD version of digester if you want to give it a go. (the java docs should explain how to make it work.)
the implementation committed has some differences from the patch supplied by Simon Kitching but some of the code was used and it certainly made my life easier (thanks simon). - robert On Tuesday, July 9, 2002, at 10:55 PM, Simon Kitching wrote: > Hi Robert/Edgar. > > I sent in a patch a while ago which I think would solve your problem. > [It was a while ago, so my memory might be misleading me]. > > There was no response; I meant to follow up but have been kind of busy > later. > See > http://marc.theaimsgroup.com/?l=jakarta-commons-dev&m=102150414316796&w= > 2 > > I'm not claiming that the patch *should* have been added; there may > well have been reasons not to.. > > As mentioned in the referenced email, there are a couple of solutions > that don't involve modifying digester: > (a) write CallMethodRules to map attributes to setter methods > instead of using SetProperties. > (b) writing an XXXBeanInfo bean properties class which specifies > attribute-name -> setter-method mappings (see java beans > documentation). > > Regards, > > Simon > >> -----Original Message----- >> From: robert burrell donkin [mailto:[EMAIL PROTECTED]] >> Sent: Wednesday, July 10, 2002 8:47 AM >> To: Jakarta Commons Users List >> Subject: Re: Digester: How to make a rule that maps an XML >> attribute to a Java Beans property with a different name? >> >> >> hi edgar >> >> i think that this ability might well be missing from digester at the >> moment. >> >> there are various ways in which this could be added. i'll >> have a think >> about which seems the best.
