public class StompSubframeDecoder extends ReplayingDecoder<StompSubframeDecoder.State>
ByteBuf
s into StompHeadersSubframe
s and StompContentSubframe
s.
maxLineLength
the maximum length of line - restricts length of command and header lines If the length of the
initial line exceeds this value, a TooLongFrameException
will be raised.
maxChunkSize
The maximum length of the content or each chunk. If the content length (or the length of each
chunk) exceeds this value, the content or chunk ill be split into multiple StompContentSubframe
s whose length
is maxChunkSize
at maximum.
If the content of a stomp message is greater than maxChunkSize
the transfer encoding of the HTTP message is
'chunked', this decoder generates multiple StompContentSubframe
instances to avoid excessive memory
consumption. Note, that every message, even with no content decodes with LastStompContentSubframe
at the end
to simplify upstream message parsing.
