Class TemplateViewRouteImpl

java.lang.Object

spark.RouteImpl

spark.TemplateViewRouteImpl

All Implemented Interfaces:

Route, Wrapper

public abstract class TemplateViewRouteImpl
extends RouteImpl

A TemplateViewRoute is built up by a path (for url-matching) and the implementation of the 'render' method. TemplateViewRoute instead of returning the result of calling toString() as body, it returns the result of calling render method. The primary purpose of this kind of Route is provide a way to create generic and reusable components for rendering output using a Template Engine. For example to render objects to html by using Freemarker template engine..
