Class TeamAppsJacksonTypeIdResolver

  • All Implemented Interfaces:
    com.fasterxml.jackson.databind.jsontype.TypeIdResolver
    public class TeamAppsJacksonTypeIdResolver
extends java.lang.Object
implements com.fasterxml.jackson.databind.jsontype.TypeIdResolver
    This TypeIdResolver provides type ids for all TeamApps UI API classes. Additionally it also provides type ids for all classes that get serialized, so they can be deserialized in the future.

    Ratio: Components are allowed to send and receive.

    On the sending side, this enables app developers to send arbitrary data for templates. E.g., a MustacheTemplate might be filled using a list of deep json structures.

    On the receiving side, this is technically not necessary, since all data that comes from UiComponents might be defined as UiObjects. However, component developers might decide to send back arbitrary object (in original or changed state) that were previously sent to the client. This approach is not recommended but possible. Since only classes that have ever been serialized can be deserialized, there is no security risk in technically allowing Object values (unless developers send security critical classes, which we regard as very unlikely).
