Examples of org.apache.tapestry.services.ResponseBuilder

org.apache.tapestry.services.ResponseBuilder
Represents the service responsible for managing all content output that is sent to the client. In the case of normal http responses this management would inlude handing out {@link IMarkupWriter} instances to render components with, as well as managing any javascript written to the output using Script templates.
This is a major internal change in terms of the way tapestry renders pages/components. Traditionally a response has been rendered via: IPage.render(writer, cycle); The logic has now changed somewhat, while the IPage.render(writer, cycle) does still happen, this service is the primary invoker of all renders, even nested component bodies. That means that in the majority of cases the ResponseBuilder service is used to invoke IComponent.render() throught the entire render cycle, creating a great deal of flexibility in terms of what can be done to control the output of a given response.

This service was primarily created to help bolster support for more dynamic content responses, such as XHR/JSON/etc - where controlling individual component output (and javascript) becomes very important when managaing client side browser state.
