public class RenderRedirectWriterImpl
extends RenderRedirectWriter

This class supports the render-redirect feature by queuing up a list of all write operations. Calling the render() method causes the queued operations to be invoked. Conversely, not calling the method will prevent the queued operations from being invoked. This is necessary because in the case of a render-redirect, any markup written to the response in the initially rendered view must be discarded.
