Other architectures that are based on layers put more emphasis on Separation of Concerns. Thus, every layer is dedicated only to a specific technical function (e.g. all domain code, all use case code, all infrastructure code). But as a result they mix in one layer all the different business processes and domains. As the code grows, it gets harder to reason about.
That leaves the bottom shadow. For that, we’ll need to re-use two of the sprites we’d previously been using for cell shadows. This will impose the tightest timing requirements upon us of anything in the design. Because we are altering the sprite graphics, the magnification, and the X coordinate, we cannot reconfigure the sprite registers until after we have finished rendering the last cell, and we’ll only have a few scanlines of space to do that work. As we’ll see once we get into the nuts and bolts, we’ll normally have dozens.

Associativity: when merging three (or more) states, it doesn’t matter which are merged first; (A ∨ B) ∨ C = A ∨ (B ∨ C). If Alice receives states from both Bob and Carol, she can merge them into her own state in any order and the result will be the same.4。业内人士推荐爱思助手下载最新版本作为进阶阅读
