I have a few classes that from my client code I need to call. Right now I have a list and then the client has to check the list for the implementation. It is a mess to use.
object Adapter {
val list = listOf(
A(),
B()
...
)
}
Ideally I would only keep one implementation in memory, but sometimes I need to change between implementations.
Make all your classes implement an interface. Since they all implement the same interface you can then assign the concrete instances to the same variable.
interface IWorker {
fun doWork()
}
Then in the Adapter class you can set which implementation you want to use.
object Adapter {
var worker: IWorker = Default()
}
Default represents any of your classes.
class Default: IWorker {
override fun doWork() {}
}
