All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.Appendable, java.lang.AutoCloseable, org.codehaus.groovy.grails.support.encoding.EncodedAppenderFactory, org.codehaus.groovy.grails.support.encoding.EncoderAware, org.codehaus.groovy.grails.web.util.GrailsWrappedWriter

public class GSPResponseWriter
extends org.codehaus.groovy.grails.web.sitemesh.GrailsRoutablePrintWriter
implements org.codehaus.groovy.grails.support.encoding.EncoderAware, org.codehaus.groovy.grails.support.encoding.EncodedAppenderFactory

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.
