All Implemented Interfaces:

Adaptable, SlingHttpServletResponse

public class JspSlingHttpServletResponseWrapper
extends SlingHttpServletResponseWrapper

The JspSlingHttpServletResponseWrapper class may be used by tag library implementors to create a RenderResponse object which wraps the writer of the response of a given page context.

Instances of this class only support writers. Trying to get an OutputStream always results in an IllegalStateException. This is the same behaviour as implemented by response wrappers of Apache Jasper.
