public class StreamContent
extends org.springframework.extensions.webscripts.AbstractWebScript

Web script 'type' that can be used when the binary data of a content property needs to be streamed back to the client as the result of executing the web script. Many of these methods have been moved into the ContentStreamer class so they can be reused by other webscripts.
