I'm not sure what you mean, but every Object has a class method which gives you it's class. irb(main):008:0\> 1.class =\> Fixnum irb(main):009:0\> 'foo'.class =\> String Alex Gutteridge Bioinformatics Center Kyoto University > **···** > > On 10 Oct 2007, at 15:24, Pokkai Dokkai wrote: > > > is it possible to convert from a ruby object to Ruby class... > > any idea..... > > -- Posted via [http://www.ruby-forum.com/\](http://www.ruby-forum.com/%5C). ---

What do you exactly have in mind ? Ruby classes are already Ruby objects ... so if you need to manipulate classes as objects you already can obj = Class.new \ instance = obj.new Sylvain > **···** > > On Wednesday 10 October 2007, Pokkai Dokkai wrote: > > > is it possible to convert from a ruby object to Ruby class... > > any idea..... ---

Maybe he means something like extracting Ruby code for the class out of the object... That would be very interesting, because you could really delve in and affect all sorts of bug fixes for compiled extensions. AFAIK, this is not possible. Take a look at ruby2ruby I'm guessing something like a = YourClass.new a.to\_ruby Ari --------------------------------------------| If you're not living on the edge, then you're just wasting space. > **···** > > On Oct 10, 2007, at 4:22 AM, Shai Rosenfeld wrote: > > > Pokkai Dokkai wrote: > > > > > is it possible to convert from a ruby object to Ruby class... > > > any idea..... > > > > do u mean this? > > > > [class Object - RDoc Documentation](http://www.ruby-doc.org/core/classes/Object.html#M000348) ---

If you want to create the class definition source code when having an instance only there is no way - at least no standard way. You would have to dig into the Ruby interpreter to do that. robert > **···** > > 2007/10/10, Pokkai Dokkai \: > > > Sylvain Joyeux wrote: > > \> On Wednesday 10 October 2007, Pokkai Dokkai wrote: > > \>\> is it possible to convert from a ruby object to Ruby class... > > \>\> any idea..... > > \> What do you exactly have in mind ?

Well, it could be sort of possible, but partly pointless: You could start a ruby process that then loads a file, but before loading, read the file. You could then create objects that contain the code (as a string, probably) for classes in the original file. Then when you ask an object, "what class are you?", you will have a little clipboard (or PDA) to lookup his/her class name and fetch your class\_code string. From there it would be possible to alter the class\_code string, then re"load" that class into the interpreter... circular? could be pointless? maybe fun? probably > **···** > > On Oct 10, 2007, at 5:50 AM, Pokkai Dokkai wrote: > > > source code here > > --------------------- > > class Name > >   def initialize > >   end > >    ..... > > end > > ----------------------- > > > > obj=Name.new > > > > now my question is ,how to create above source code from obj?. > > > > actually jruby will create java object to ruby object > > but that ruby object(from java object) is not in source code format > > > > so i am asking this question ...... > > -- Posted via [http://www.ruby-forum.com/\](http://www.ruby-forum.com/%5C).
