Interface View

All Known Implementing Classes:

AbstractView

public interface View

MVC View for a web interaction. Implementations are responsible for rendering content, and exposing the model. A single view exposes multiple model attributes.

This class and the MVC approach associated with it is discussed in Chapter 12 of Expert One-On-One J2EE Design and Development by Rod Johnson (Wrox, 2002).

View implementations may differ widely. An obvious implementation would be JSP-based. Other implementations might be XSLT-based, or use an HTML generation library. This interface is designed to avoid restricting the range of possible implementations.

Views should be beans. They are likely to be instantiated as beans by a ViewResolver. As this interface is stateless, view implementations should be thread-safe.

public void render(Map model, HttpServletRequest request, HttpServletResponse response)
             throws java.lang.Exception

Render the view given the specified model. The first step will be preparing the request: In the JSP case, this would mean setting model objects as request attributes.

Parameters:

model - Map of model attributes (model name String mapped to model object)

request - current HTTP request

response - HTTP response we are building

Throws:

Exception - if rendering failed
