10/07/2018, 9:38 PMYes, you almost never have to subclass scopes. There are some situations where it's useful though, but let's not talk about them 🙂 hehe - a

10/07/2018, 9:38 PMhahaha okay - a
amanda.hinchman-dominguez
10/07/2018, 9:39 PMhere is my other point of confusion - so, we don't need to subclass scopes. Here, we have an model, which is a subset of whatever is there - how do we know whether what we have is a subset of something or not? - a

10/07/2018, 9:43 PM@amanda.hinchman-dominguez Take a look at the video, maybe that makes it clearer 🙂 - e

10/07/2018, 9:55 PMLooking at your video, the most important part for me was the edit function part - e
edvin
10/07/2018, 9:55 PMHaha 🙂 - e
edvin
10/07/2018, 9:55 PMI can do another one tomorrow with some elaboration. It's midnight now so I should get to bed 🙂 - a
amanda.hinchman-dominguez
10/07/2018, 9:55 PMYou create the model, you have your scope - and what helped was looking into the source code of course - a
amanda.hinchman-dominguez
10/07/2018, 9:56 PMScopedInstance is literally an empty interface - a
amanda.hinchman-dominguez
10/07/2018, 9:57 PMThat seems to be the specific part that helps us group these components together - e
edvin
10/07/2018, 9:57 PMYeah, it's just a marker instance. We should be explicit about what we allow to be put into scopes, but it should be easy to do so. Most of the time though, you won't have to add
to your classes, just wrap them in aScopedInstance
, or much better if you have just a single property: AnViewModel
.ItemViewModel - e
edvin
10/07/2018, 9:57 PMThat's what I did here. - a
amanda.hinchman-dominguez
10/07/2018, 9:58 PMAlright haha I'll let you go to bed, I'll stick up the diagram I come up with for feedback later! - e
edvin
10/07/2018, 9:59 PMSweet! - a

10/07/2018, 10:27 PMFirst attempt - this reminds me a lot of Context between Activities and Fragments in Android! - a
amanda.hinchman-dominguez
10/07/2018, 10:28 PMunfortunately, this only captures the ModelViewItem/ViewItem instance - it would be good to tackle a scopes diagram that handles requiring you to create your own ScopedInstance as well. - a
amanda.hinchman-dominguez
10/07/2018, 10:37 PMBy the way, I was looking into the use of empty interfaces - for anyone curious, I really liked these explanations - a

10/08/2018, 6:08 AM@amanda.hinchman-dominguez There are so few cases where it makes sense. I Can't even think of a reason to create your own ScopedInstance right now 🙂
