- Object binary data. This parameter can be null, if object binary data is not generated yet.semanticName

java.lang.String getUrl(int id, int referrer)

returned LinkEmbedDecision.Embed
but embedding is impossible.
Can be called multiple time for same object id.
id
- Object id. This id is saving operation-wide unique.referrer
