Class HttpChunkLineValidatingByteProcessor

java.lang.Object

io.netty.handler.codec.http.HttpChunkLineValidatingByteProcessor

All Implemented Interfaces:

ByteProcessor

final class HttpChunkLineValidatingByteProcessor
extends java.lang.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.

   chunk-data     = 1*OCTET ; a sequence of chunk-size octets

                       [ BWS "=" BWS chunk-ext-val ] )

Method Detail

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()
