## org.codehaus.groovy.grails.web.pages
[Java] Class GSPResponseWriter

    java.lang.Object
      java.io.Writer
          java.io.PrintWriter
              org.codehaus.groovy.grails.web.util.GrailsPrintWriterAdapter
                  org.codehaus.groovy.grails.web.sitemesh.GrailsRoutablePrintWriter
                      org.codehaus.groovy.grails.web.pages.GSPResponseWriter

All Implemented Interfaces:
  EncodedAppenderFactory, EncoderAware

    public class GSPResponseWriter
    extends GrailsRoutablePrintWriter

NOTE: Based on work done by on the GSP standalone project (https://gsp.dev.java.net/) A buffered writer that won't commit the response until the buffer has reached the high water mark, or until flush() or close() is called. Performance optimizations by Lari Hotari, 13.03.2009 Calculating the Content-Length has been disabled by default since Jetty ignores it (uses Chunked mode anyways). Content-Length mode can be enabled with -DGSPResponseWriter.enableContentLength=true system property.
