in thread Feedback on Class::Container

Class::MethodMaker has a method maker called "object" that declares a slot to be of a particular object type. For example: 

use Class::MethodMaker
    new_hash_init => 'new',
    object        => [ HTML::Mason::Lexer => 'lexer' ];

You can then choose to proxy selected methods from the contained class. For example, to create a class called CGI::Simple that contains a CGI.pm object in a slot called 'query' and proxies new() and param() to it: 

package CGI::Simple;

use Class::MethodMaker
    new_hash_init => 'new',
    object        => [ CGI => {
                                 slot       => 'query',
                                 comp_mthds => [ 'new',
                                                 'param' ],
                               }
                      ];

This seems just nextdoor to your module to me.

    Oh, I see. Thanks for the clarification. However, this seems quite orthogonal to Class::Container. One might want to use Class::Container to create the objects with the proper parameters, then use Class::MethodMaker to create interfaces to the objects, possibly using the proxies Class::MethodMaker provides.

    It's quite possible that someone would want to use both in the same project, but that doesn't suggest to me that they should be in the same module.

      Given the width of the Class::MethodMaker API I'd be surprised if any OO method generation was truly orthoganal to it! After all, the main purpose of your module is to provide a new() for sub-classes that performs certain convenient functions with respect to composition. That sounds a lot like the what many of the method makers in Class::MethodMaker do already.

      However, I'm not meaning to suggest that having Class::Container as a separate module is bad. People may want to use it who have no need for the larger functionality of Class::MethodMaker.

      As I understood your question, you asked if your new module fit anywhere in the existing OO landscape. I happen to think it does. Whether you choose to put it where I think it might fit is another question entirely.
