A simple consistency manager implementation on Kotlin. You can subscribe on some class changes, and notify subscribers about that class being updated. Convinient when you have data being displayed in many different places and you need it up to date any time it changes, eg. somebody is making item favorite and 'star' icons should update everywhere
interface ConsistencyManagerContract {
fun notifyUpdateModel(model: Any)
fun notifyUpdateClass(kclass: KClass<*>)
fun subscribe(modelClass: KClass<*>, callback: WeakReference<(Any?) -> Unit>)
}
class ConsistencyManager : ConsistencyManagerContract {
private val subscriptionsMap: MutableMap<KClass<*>, MutableList<WeakReference<(Any?) -> Unit>>> = mutableMapOf()
override fun notifyUpdateModel(model: Any) {
