How to get all attributes in VaadinSession

Vaadin 6 / 7 / 8

Dear,

Are there any ways to get all the attributes stored in VaadinSession? like the method of getAttributeNames in HttpSesion?

Many thanks,
Joey

Hi,

unfortunately it looks like no - the attributes map is even private, so you can’t access it in a subclass.

Hi,

Any chance that you might be able to implement that method? It might be helpful.

Best regards,

I can’t be certain, but I think it’s been left out on purpose. From what I can tell, the only places that add attributes in the Framework are a few internal attributes that you wouldn’t really want to override -
PRESERVE_UNBOUND_SESSION_ATTRIBUTE in VaadinService, color picker history and LegacyApplicationUIProvider.

If you add attributes to the session yourself, you should at least have the keys that you can check for.
