In traditional Java, you're probably using Jackson for your JSON. You can achieve those sorts of results by specifying the classes and type tags in annotations on an abstract Either class to use Jackson's polymorphic serialization feature.
- balefrost 5y agoThe point of sealed classes is that you have a known number of possible representations. So you can have `when` blocks that exhaustively check all possibilities. Having an open class hierarchy would not work for that purpose.
