public interface View
HandlerResult
to the HTTP response.
In contrast to an Encoder
which is a singleton and encodes any object of a given type, a View
is typically selected by name and resolved using a ViewResolver
which may for example match it to an HTML template. Furthermore a View
may render based on multiple attributes contained in the model.
A View
can also choose to select an attribute from the model use
any existing Encoder
to render alternate media types.
