ENCODING
protected static final ByteChunk ENCODING
ENCODING_NAME
protected static final String ENCODING_NAME
buf
protected byte[] buf
Read bytes buffer.
buffer
protected InputBuffer buffer
Next buffer in the pipeline.
endChunk
protected boolean endChunk
Flag set to true when the end chunk has been read.
lastValid
protected int lastValid
Last valid byte in the buffer.
needCRLFParse
protected boolean needCRLFParse
Flag set to true if the next call to doRead() must parse a CRLF pair
before doing anything else.
pos
protected int pos
Position in the buffer.
readChunk
protected ByteChunk readChunk
Byte chunk used to read bytes.
remaining
protected int remaining
Number of bytes remaining in the current chunk.
doRead
public int doRead(ByteChunk chunk,
Request req)
throws IOException
Read bytes.
- doRead in interface InputFilter
- doRead in interface InputBuffer
- If the filter does request length control, this value is
significant; it should be the number of bytes consumed from the buffer,
up until the end of the current request body, or the buffer length,
whichever is greater. If the filter does not do request body length
control, the returned value should be -1.
end
public long end()
throws IOException
End the current request.
- end in interface InputFilter
parseCRLF
protected boolean parseCRLF()
throws IOException
Parse CRLF at end of chunk.
parseChunkHeader
protected boolean parseChunkHeader()
throws IOException
Parse the header of a chunk.
parseEndChunk
protected boolean parseEndChunk()
throws IOException
Parse end chunk data.
FIXME: Handle trailers
readBytes
protected int readBytes()
throws IOException
Read bytes from the previous buffer.
recycle
public void recycle()
Make the filter ready to process the next request.
- recycle in interface InputFilter
