RE: [juddi-Developers] Handlers

[Steve Viens <sv...@attbi.com>]

Anou, the reason just came back to me... 

The idea was to reduce the number of Handler objects created. jUDDI only
really needs one shared instance of each handler since a handler doesn't
maintain state - and that instance is created and stored in the shared
HandlerMaker instance.

My thought was to attempt to enforce the 'correct' way to obtain a
Handler implementation was via the HandlerMaker instance. By making each
Handler implementation's constructor 'protected' we're ensured that a
developer couldn't do this:

  Handler h = new org.juddi.handler.FindServiceHandler();

Instead, every handler should be added to the HandlerMaker 'handler
registry' (i.e. HashMap) and that the 'correct' way to obtain a handler
was through the HandlerMaker.lookup(String) method. For instance, you
could obtain the 'FindService' handler by making any of these calls:

  Handler h = HandlerMaker.lookup("find_service");
  Handler h =
HandlerMaker.lookup(org.juddi.handler.FindService.TAG_NAME);
  Handler h =
HandlerMaker.lookup("org.juddi.datatype.request.FindService");
  Handler h =
HandlerMaker.lookup(org.juddi.datatype.request.FindService.class.getName
());

Nope

I may have had some fleeting reason for it but that's long gone now ...
Do what you have to do!

Steve,

Any reason why the Handler constructors are made protected in this
release ?

regards,
