Method Details

doWrite

public int doWrite(ByteChunk chunk,
                   Response res)
            throws IOException
Write some bytes.
Specified by:
doWrite in interface OutputFilter
doWrite in interface OutputBuffer

Returns:
number of bytes written by the filter


end

public long end()
            throws IOException
End the current request. It is acceptable to write extra bytes using buffer.doWrite during the execution of this method.
Specified by:
end in interface OutputFilter


getContentLength

public long getContentLength()
Get content length.


getEncodingName

public ByteChunk getEncodingName()
Return the name of the associated encoding; Here, the value is "identity".
Specified by:
getEncodingName in interface OutputFilter


getRemaining

public long getRemaining()
Get remaining bytes.


recycle

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


setBuffer

public void setBuffer(OutputBuffer buffer)
Set the next buffer in the filter pipeline.
Specified by:
setBuffer in interface OutputFilter


setResponse

public void setResponse(Response response)
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
