This project is a simple implementation of a Composite Pattern and how it can be helpful in our projects.
To use the package, clone and run it!
Project inclused 3 Packages and a project.
Domain: which is the subject area on which the application is intended to apply.
Networking: which is the networking layer which is responsible to pass the data or error. In this package, I hardcoded the returned data to reach the behaviour we have in mind.
ImageLoaderWithFallbackComposite: which is the implementation of simple networking to load some images from server/backend, which is done withing composite pattern in TDD
CompositePatternExample: which is the app that uses those packages, and implement the image loader. The interesting part here is that I want the app to fetch for the image 2 times from the local and if it failed, then tries to fetch the image from remote url.
Therefore I have implemented it as this way:
let contentView = UIComposer.viewComposedWith(imageLoader: ImageLoaderWithFallbackComposite(
primary: LocalImageLoader(),
fallback: ImageLoaderWithFallbackComposite(
primary: LocalImageLoader(),
fallback: RemoteImageLoader())))
As you can see, for the fallback loader, I also injected the image loader with local loader as primary and remote loader as fallback.
Pull requests are welcome.
