Builder Design Pattern In C++

Hi everyone, Don't forget to hit LIKE and SUBSCRIBE button for more videos like this!! And this will help me a-lot.

[@aseemsameer7281]

How is this constructing a complex object using other objects? No other complex objects being created to create a single complex object, whatsoever. Just implementing the Factory-similar setup, with the virtual constructor, isn't rather convincing, than justified as a new design pattern. Appreciate the simplicity in explanation, though.

i will vote you for the best actor in tech teaching category. your voice goes up and down and be really emotional. you really get into it.

[@CppNuts]

Thank you so much for such a great comment!! :)

[@anantupadhyay4884]

as per your explanation , each and every builder needs to override all functions. Builder don't behaves in this way. Suppose if some concrete builder only needs 2 composite objects and other concrete builder needs 3 composite objects. For simple example, Manual Car needs Seat, Engine and Automatic Car needs Seat , Engine, any other feature(Sun Roof). How will your explanation handle this ? Please explain

[@SajalKishoreRastogi]

Exactly. What is described in the video is (partly) Abstract Factory Design Pattern with a few elements of Builder Design Pattern sprinkled on it. It is a completely new design patterns which seems to accomplish nothing - neither the easy maintenance of Abstract Factory, nor the flexible (and consistent) object creation of Builder.

[@anuraagkhandagle5130]

Hi, it was a good explanation. I'm struggling to find the difference between abstract factory and builder pattern here. Can you make a video where you take the same example for both Abstract Factory and Builder pattern and tell us which to use when? I'm seeing this as an analogy to abstract factory. Where Director is equivalent to Factory class. Jet Builder and Propellor Builder can be considered as two Factories. I'm not understanding what the difference would be.

[@varunsingh3825]

Hi, Nicely explained, can you please UML diagrams also, at least for design pattern related topics? Please keep helping :)

[@CppNuts]

Hi Varun Singh, UML Link is in the description field.

[@habibyama]

You make me understand in 8 minutes. Lots of love :)

[@sandrok14]

Nice explanation as always. But I don't think we need to delete jet and pro pointers, because they are just stack pointers no heap memory used. Correct me if I am wrong.

[@CppNuts]

delete is required, notice that we are returning heap pointer and assigning into jet and pro pointers. If it is hard to find whether you need to use delete or not then just check do you have any new operator in your program if yes then you actually need to have delete keyword in your program somewhere which is delete the heap memory created using new operator.

[@sandrok14]

@@CppNuts Ok.. Now following the hierarchy I get it. But from main() perspective it seemed like stack pointers, a bit confusing

[@ankitgupta8215]

Hey please add UML or class diagram for same..it will be an added advantage to viewers,design patterns should start with some class diagram...its a great help....thanx.

[@ankitgupta8215]

thanks..it will work for many.

[@shibisaketh]

Abstract factory and factory method also very similar to builder. So can u compare this 3 and tell when to use what

[@trodisdeer5281]

Please add more videos about Design Patterns in C++. Thank you .

[@CppNuts]

Yes it is planned, but will take time.

[@varunsingh3825]

Hi Ethan, I really liked your question and explanation, thanks alot :) Can you please add a detail video explaining the internals of virtual table implementation I mean how table created, how functions stored, how vptr iterate through table, whats if offset , how exactly it find to which tale and which will be called at runtime using vtable??

[@CppNuts]

Hi Varun, You can expect in coming videos!!

[@techademy9354]

Hey sir, you have any plans to complete the design patterns course? or any plans to make like full course on sites like Udemy or anything like that? Thanks :)

[@vhxhao]

Thanks for the nice video. What happens if Jetbuilder needs an extra step than PropellerBuilder? what do we do in the Director class?

[@mayur07ec78]

Nice explanation of all the creational design patterns but not able to find structural and behavioral design patterns. May I know are you planning to upload in short time or have to wait long time ?

[@CppNuts]

Hi mayur patel, I am trying my best to upload videos ASAP. But i think you may have to wait for little longer i guess. i have few play lists to complete first.

[@mayur07ec78]

CppNuts Sure, take your time, awaiting for more videos, Thank you ...

[@hsaidinsan6345]

Great work man But why have you stopped making more design patterns videos If because of your busy program, then pls try to assign some of your time for this important topic

[@CppNuts]

Sure, i will think about it, thanks man!

[@saikumarpeddireddy7079]

[@FabioBannet]

Very useful lesson, but - please speak slowly (because you tong like " do know do way" ), and please don`t repeat all time word - " OK" it`s not good. Thank you ^)

[@CppNuts]

Thanks for your suggestion, i have already tried to take care of these two problems. :😀

[@rohitashkumar781]

in your github code code showing error:- BuilderDesginPattern.cpp:58:5: error: ‘Builder’ does not name a type; did you mean ‘JetBuilder’? Builder *builder; ^~~~~~~ JetBuilder

[@CppNuts]

Thanks!! Its corrected please check!!

[@TriNguyen-og1ws]

Nice vid, thanks alot bro

[@aswinsree3570]

Your C++ and STL videos are superb but those on Design Patterns are junk (considering the high standard you have set before). Showing code doesn't even help. My suggestion is to explain with diagrams first. UML diagrams do help.

[@CppNuts]

Design patterns videos r the one i recorded in the beginning, and i was learning that time. I hope you will understand.
