java.lang.Object

javax.servlet.ServletResponseWrapper

javax.servlet.http.HttpServletResponseWrapper

com.adobe.acs.commons.util.BufferedHttpServletResponse

All Implemented Interfaces:

Closeable, AutoCloseable, javax.servlet.http.HttpServletResponse, javax.servlet.ServletResponse

public class BufferedHttpServletResponse
extends javax.servlet.http.HttpServletResponseWrapper
implements Closeable

A wrapper around a HttpServletResponse which buffers all output being written to getOutputStream() or getWriter(). The response cannot be committed via flushBuffer() but only via close(). Access to the underlying buffer is provided via getBufferedServletOutput().
