Interface Models

All Superinterfaces:
Iterable<String>
public interface Models extends Iterable<String>

A map of name to model instances used by a ViewEngine to process a view. Instances implementing this interface must be injectable using Inject and are RequestScoped.

Note that certain view engines, such as engines for Jakarta Server Pages and Facelets, support model binding via Named in which case the use of Models is optional.
