Did you read the code and comments? Not at all. I don't want use inheritance because I won't all methods and properties from Array[] in the PeopleList interfaz. Hence, I have to use aggregation (composition, delegation). If I use inheritance, the clients of PeopleList could do bad things or things that have no sense (as the case), e.g. PeopleList.Fill PeopleList.Push PeopleList.Pop This isn't the best example. But if you think about a minute, you will catch it. Do not focus on the example, because really, what I want isn't to add to a class methods from an array (that's just an example). I looking for a design pattern that allows me to solve a typical problem. That problem could be described as "How to add methods from a helper object without have to rewrite a wrapper for each method (with just a call within) in the host class?". -- Fabián Flores Vadell www.comoprogramarcongambas.blogspot.com www.speedbooksargentina.blogspot.com ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user
