All Implemented Interfaces:

HttpServletResponse, ServletResponse, 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.

Constructor Details

JspSlingHttpServletResponseWrapper

public JspSlingHttpServletResponseWrapper(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.

• TagUtil.getResponse(PageContext)

Method Details

getWriter

public PrintWriter getWriter()

Returns the writer for this response wrapper.

Specified by:

getWriter in interface ServletResponse

Overrides:

getWriter in class ServletResponseWrapper

Returns:

a PrintWriter object that can return character data to the client

getOutputStream

public ServletOutputStream getOutputStream()

Throws an IllegalStateException as this wrapper only supports writers.

Specified by:

getOutputStream in interface ServletResponse

Overrides:

getOutputStream in class ServletResponseWrapper

Returns:

a ServletOutputStream for writing binary data

See Also:

• ServletResponse.getWriter()

resetBuffer

public void resetBuffer()

Resets the buffer of the JspWriter underlying the writer of this instance.

Specified by:

resetBuffer in interface ServletResponse

Overrides:

resetBuffer in class ServletResponseWrapper
