Method Detail

doWrite

public int doWrite(ByteChunk chunk,
                   Response res)
            throws IOException

Write some bytes.

Specified by:

doWrite in interface OutputFilter

Specified by:

doWrite in interface OutputBuffer

Parameters:

chunk - Data to write

res - Used to allow buffers that can be shared by multiple responses.

Returns:

number of bytes written by the filter

Throws:

IOException

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

setBuffer

public void setBuffer(OutputBuffer buffer)

Set the next buffer in the filter pipeline.

Specified by:

setBuffer in interface OutputFilter

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

Returns:

Should return 0 unless the filter does some content length delimitation, in which case the number is the amount of extra bytes or missing bytes, which would indicate an error. Note: It is recommended that extra bytes be swallowed by the filter.

Throws:

IOException

recycle

public void recycle()

Make the filter ready to process the next request.

Specified by:

recycle in interface OutputFilter

getEncodingName

public ByteChunk getEncodingName()

Return the name of the associated encoding; Here, the value is "identity".

Specified by:

getEncodingName in interface OutputFilter
