      • doWrite

        public int doWrite​(ByteBuffer chunk)
                    throws IOException
        Description copied from interface: OutputBuffer
        Write the given data to the response. The caller owns the chunks.
        Specified by:
        doWrite in interface OutputBuffer
        Parameters:
        chunk - data to write
        Returns:
        The number of bytes written which may be less than available in the input chunk
        Throws:
        IOException - an underlying I/O error occurred
      • getBytesWritten

        public long getBytesWritten()
        Description copied from interface: OutputBuffer
        Bytes written to the underlying socket. This includes the effects of chunking, compression, etc.
        Specified by:
        getBytesWritten in interface OutputBuffer
        Returns:
        Bytes written for the current request
      • flush

        public void flush()
                   throws IOException
        Added to allow flushing to happen for the gzip'ed outputstream
        Specified by:
        flush in interface HttpOutputBuffer
        Throws:
        IOException - If an I/O error occurs while flushing
      • setResponse

        public void setResponse​(Response response)
        Description copied from interface: OutputFilter
        Some filters need additional parameters from the response. All the necessary reading can occur in that method, as this method is called after the response header processing is complete.
        Specified by:
        setResponse in interface OutputFilter
        Parameters:
        response - The response to associate with this OutputFilter
      • setBuffer

        public void setBuffer​(HttpOutputBuffer buffer)
        Description copied from interface: OutputFilter
        Set the next buffer in the filter pipeline.
        Specified by:
        setBuffer in interface OutputFilter
        Parameters:
        buffer - The next buffer instance
      • recycle

        public void recycle()
        Make the filter ready to process the next request.
        Specified by:
        recycle in interface OutputFilter
