Method Detail

handleRead

public NextAction handleRead(FilterChainContext ctx)
                      throws IOException

The method is called once we have received a single String line. Filter check if it's MultiLinePacket terminating line, if yes - we assume MultiLinePacket completed and pass control to a next Filter in a chain. If it's not a terminating line - we add another string line to a MultiLinePacket and stop the request processing until more strings will get available.
