/**
|
|
* Created by charlag on 12/07/2017.
|
|
*
|
|
* Class to represent data required to display either a notification or a placeholder.
|
|
* It is either a {@link Placeholder} or a {@link Concrete}.
|
|
* It is modelled this way because close relationship between placeholder and concrete notification
|
|
* is fine in this case. Placeholder case is not modelled as a type of notification because
|
|
* invariants would be violated and because it would model domain incorrectly. It is prefereable to
|
|
* {@link com.keylesspalace.tusky.util.Either} because class hierarchy is cheaper, faster and
|
|
* more native.
