| todo‑mvp | Demonstrates a basic Model‑View‑Presenter (MVP) architecture and provides a foundation on which the other samples are built. This sample also acts as a reference point for comparing and contrasting the other samples in this project. |
Model–view–presenter
Diagram that depicts the Model View Presenter (MVP) GUI design pattern.
Model–view–presenter (MVP) is a derivation of the model–view–controller (MVC) architectural pattern, and is used mostly for building user interfaces.
In MVP, the presenter assumes the functionality of the “middle-man”. In MVP, all presentation logic is pushed to the presenter.[1]
