Message: [QUOTE="Sam Kong, post: 4498093"] Hi, folks! What's the easiest(simplest) code to find a class/module that first defines a specific method? I became curious while I was looking for a document of Array#partition method. Actually the method is defined in Enumerable module. But I couldn't guess that it was defined there until I checked Array class's doc first. If the inheritance(or mixin) hierarchy is very complex, it will take long to find a method. The one I can think of is using MyClass.ancestors and MyClass.instance_methods recursively (or repeatedly). Is there a better way? (On my second thought, singleton classes should also be considered, right?) The method prototype might be like... #returns a class or module which defines the method def defined_where(obj, method_name) ... end Thanks. Sam [/QUOTE]
