Vaadin TimeLine addon API / Documentation

Could someone please tell me where I can find TimeLine Addon API/Documentation?

Thanks,

If you mean the
Vaadin Timeline add-on
(commercial or AGPL license), there is a PDF manual inside the ZIP download.

I am not aware of a separate javadoc download, but the JAR file contains the source code including comments, so your IDE can probably display javadoc based on it.

Thanks. That PDF is quite informational.
