All Implemented Interfaces:

public class JspSlingHttpServletResponseWrapper
extends org.apache.sling.api.wrappers.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.

Constructor Detail

JspSlingHttpServletResponseWrapper

public JspSlingHttpServletResponseWrapper(javax.servlet.jsp.PageContext pageContext)

Creates an instance of this response wrapper for the given pageContext. The original JspWriter is retrieved from the page context calling the PageContext.getOut() method. The delegatee RenderResponse is retrieved from the page context by calling the TagUtil.getResponse(PageContext) method.

Parameters:

pageContext - The PageContext to use to get the original output stream and the delegatee response.
