Interface View

All Known Implementing Classes:

AbstractUrlBasedView, AbstractView, FreeMarkerView, HttpMessageWriterView, RedirectView, ScriptTemplateView

public interface View

Contract to render 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.
