Thank you for the simple explanation on the decorator pattern :) that was very helpful

The cost for the ExpressoShotDecorator should be Cost = decorator.Cost + .55M;

Hi, nice explanation, thanks for sharing this. In the next videos it would be great to also have an example how the client would use this.

Very very nice design patterns series ... Very nice real life examples and explanation by Philip .. thanks for posting such informative vedio .. plz post more designs patterns vedio

Clear and excellent explanation. Thanks!

Fantastic video. Thank you!

Phil is very precise with words even on a casual statement. Robert has a tough time . Haha I've seen Phil correct Roberts statements at least a dozen times. but this is just friendly corrections. :). Best videos in the internet for Design patterns. 👍😎

Yeh total clash but it works

Why almost all of the videos about decorator pattern talks about coffe shop..of course bcos the book uses coffe shop as the example

Thanks, very well explained.

In the example with espresso, it seems that we duplicate the Ingredients list each time we add a decorator (each decorator maintains its own list of ingredients which contains all previous strings plus a new one). Why we can't add to BaseCoffee class the List private field and public methods that allow us to add elements in and retrieve information from this list. In this manner it could be similar to the event system. In general, if I suppose that my object can be modified then I add the property which stores the list of applied modifiers and some method that iterates over this list to define a final state of the object.

Thank you, very clear.

It would be really helpful if you guys could make a video on Code to interface and unity framework(ioc) topics

How is the coffe example a decorator example and not a composite?

Hello! I've got one question. In the EspressoShotDecorator we stack up all the decorated coffe ingredients plus the espresso. But for the cost we just add .55 to our cost, without considering the decorated coffee cost. This way, the espresso shot is gonna cost 0+.55 I think.... Or am i missing anything? Nice Tutorial by the way! Cheers! Antonio

4 years late but whatever. The first instance of the coffee "BaseCoffee" has a price of 1.50, and when you decorate it with the espresso you add .55 to that, totaling 2.05. As far as I know you will always need an instance if ICoffee in order to create a espresso, so you can't just instanciate an espresso by itself.

Yes like he said it’s an onion and each layer is changing the previous value.

I like these 2 doing videos.

I couldn't find the link to the design pattern playlist, could someone please link? Thank you! Edit: Found it kzread.info/head/PLT2NrqLzZng3YMek58eVZVkBiW3NyVSef

thanks

nice info guy's but maybe next time get a maybe a diagram , or even some uml schematic .. just the code allone makes it hard to follow Judith Bishop did a nice book on the subject years ago "C# 3.0 Design Patterns" published by O'Reilly

Hard disagree. Everybody else puts up Visio slides labelled A and B, while these two have a CONVERSATION and talk with their hands. It's brilliant, and easy to follow, for me at least.

Subsystem for the particula functionality, in short

Oh, ok, so the decorator pattern is something similar to the ECS

Guys, that's gonna mount to an ungodly amount of classes... @_@ I'm getting dizzy.

I didn't understand fully

Because everyone decorates an onion. Facepalm.
