public class StompSubframeDecoder extends ReplayingDecoder<StompSubframeDecoder.State>
ByteBufs into StompHeadersSubframes and StompContentSubframes.
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 StompContentSubframes 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.
