how to retrieve the right object (user or group) with a param UserOrGroupDataType inside a plugin (function) ?

Question

Hello, 
 
 I'm trying to implement functions to check the permissions of a group or a user (first param) on a specific folder or document (second param) but i'm stuck with the UserOrGroupDataType coming as a string. 
 How could i make the distinction between the two kinds of objects inside the java code of the plugin ? 
 Regards

 @Function public Boolean hasAdminRightOnDocument(ContentService _cs, UserService us, GroupService gs, @Parameter(required = true) @DocumentDataType @Name("document_to_check") Long documentId, @Parameter(required = false) @UserOrGroupDataType @Name("user_or_group") TypedValue userorGroup
