encodeJsonTree method

@override Object? encodeJsonTree(T instance)

Converts instance to a JSON tree.

Before calling this method, you should call isInstance to check whether instance is an instance of T .

Implementation

@override
Object? encodeJsonTree(T instance) {
  if (instance == null) {
    return null;
  }
  final kind = findKindByInstance(instance);
  final name = kind.name;
  final jsonTree = kind.encodeJsonTree(instance);
  if (jsonTree is Map) {
    assert(jsonTree[jsonDiscriminator] == null);
    jsonTree[jsonDiscriminator] = name;
    return jsonTree;
  } else {
    return {
      jsonDiscriminator: name,
      'value': jsonTree,
    };
  }
}
