Method Detail

doWrite
public int doWrite(ByteBuffer chunk) throws IOException
Description copied from interface:OutputBufferWrite the given data to the response. The caller owns the chunks.- Specified by:
doWritein interfaceOutputBuffer- 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:OutputBufferBytes written to the underlying socket. This includes the effects of chunking, compression, etc.- Specified by:
getBytesWrittenin interfaceOutputBuffer- Returns:
- Bytes written for the current request
-
setResponse
public void setResponse(Response response)
Description copied from interface:OutputFilterSome 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:
setResponsein interfaceOutputFilter- Parameters:
response- The response to associate with this OutputFilter
-
setBuffer
public void setBuffer(HttpOutputBuffer buffer)
Description copied from interface:OutputFilterSet the next buffer in the filter pipeline.- Specified by:
setBufferin interfaceOutputFilter- Parameters:
buffer- The next buffer instance
-
flush
public void flush() throws IOExceptionDescription copied from interface:HttpOutputBufferFlushes any unwritten data to the client.- Specified by:
flushin interfaceHttpOutputBuffer- Throws:
IOException- If an I/O error occurs while flushing
-
end
public void end() throws IOExceptionDescription copied from interface:HttpOutputBufferFinish writing the current response. It is acceptable to write extra bytes usingOutputBuffer.doWrite(java.nio.ByteBuffer)during the execution of this method.- Specified by:
endin interfaceHttpOutputBuffer- Throws:
IOException- If an I/O error occurs while writing to the client
-
recycle
public void recycle()
Description copied from interface:OutputFilterMake the filter ready to process the next request.- Specified by:
recyclein interfaceOutputFilter
