Class HttpChunkLineValidatingByteProcessor

java.lang.Object

io.netty.handler.codec.http.HttpChunkLineValidatingByteProcessor

All Implemented Interfaces:

ByteProcessor

final class HttpChunkLineValidatingByteProcessor
extends Object
implements ByteProcessor

Validates the chunk start line. That is, the chunk size and chunk extensions, until the CR LF pair. See RFC 9112 section 7.1.

                   last-chunk

  chunk          = chunk-size [ chunk-ext ] CRLF
                   chunk-data CRLF
  chunk-size     = 1*HEXDIG
  last-chunk     = 1*("0") [ chunk-ext ] CRLF

  chunk-data     = 1*OCTET ; a sequence of chunk-size octets
  chunk-ext      = *( BWS ";" BWS chunk-ext-name
                      [ BWS "=" BWS chunk-ext-val ] )

  chunk-ext-name = token
  chunk-ext-val  = token / quoted-string
  quoted-string  = DQUOTE *( qdtext / quoted-pair ) DQUOTE
  qdtext         = HTAB / SP / %x21 / %x23-5B / %x5D-7E / obs-text
  quoted-pair    = "\" ( HTAB / SP / VCHAR / obs-text )
  obs-text       = %x80-FF
  OWS            = *( SP / HTAB )
                 ; optional whitespace
  BWS            = OWS

Method Details

process

public boolean process(byte value)

Specified by:

process in interface ByteProcessor

Returns:

true if the processor wants to continue the loop and handle the next byte in the buffer. false if the processor wants to stop handling bytes and abort the loop.

finish

public void finish()
