All Implemented Interfaces:

Message

public class CanReply
extends AbstractMRReply

Base class for replies in a CANbus based message/reply protocol.

It is expected that any CAN based system will be based upon basic CANbus concepts such as ID (standard or extended), Normal and RTR frames and a data field.

"header" refers to the full 11 or 29 bit header; which mode is separately set via the "extended" parameter

CBUS uses a 2-bit "Pri" field and 7-bit "ID" ("CAN ID") field, with separate accessors.
