FramerFramer will read a few bytes in an effort to
figure out if the incoming data may be something it recognizes. E.g., a
HTTP Framer could check if the first bytes match "GET", "POST",
"PUT" and "DELETE" if if so assume that the payload indeed is HTTP and
therefore return true. Of course, you may never really know until you
actually have parsed the entire body but this method should return quick
and if turns out that the data isn't what it thought, throw an exception
and the framework will take care of it.accept in interface Framer<Packet,IPv4Packet>data - the data to check whether it could be a frame of this typeCopyright © 2021. All Rights Reserved.
