Class GZIPResponseStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
    public class GZIPResponseStream
extends javax.servlet.ServletOutputStream
    This is an implementation of a ServletOutputStream which uses a GZIPOutputStream to provide gzip compression for a HttpServletResponse (see GZIPResponseWrapper).

      Constructor Description
      GZIPResponseStream​(javax.servlet.http.HttpServletResponse response, boolean captureText)
      Creates a new GZIPOutputStream which is an implementation of a ServletOutputStream which uses a GZIPOutputStream to provide gzip compression for a HttpServletResponse (see GZIPResponseWrapper).

    • Method Summary

      All Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      protected java.lang.String applyRegExp​(java.lang.StringBuilder complete)  
      void close()
      Closes this stream (which implies finishing the underlying GZIPOutputStream, adding correct response headers and flushing/closing the outputstream).
      boolean closed()
      Returns true if this stream has been closed (using close()).
      protected boolean filterOutput()  
      void flush()
      Flushes this stream (and thus flushes the underlying GZIPOutputStream).
      boolean isReady()  
      void setWriteListener​(javax.servlet.WriteListener writeListener)  
      void write​(byte[] b)
      Writes the given byte array to this stream (and thus to the underlying GZIPOutputStream).
      void write​(byte[] b, int off, int len)
      Writes the given byte array to this stream (and thus to the underlying GZIPOutputStream).
      void write​(int b)
      Writes the given byte to this stream (and thus to the underlying GZIPOutputStream).
