much more object oriented and encapsulated. The biggest addition is that it is now possible to support multiple DBC files being loaded at once with each file associated to one or both buses. Note that currently the program still does not support multiple DBC files but the groundwork is there.

/*classes to encapsulate data from a DBC file. Really, the stuff of interest

are the nodes, messages, signals, attributes, and comments.
|
|
|
|
These things sort of form a hierarchy. Nodes send and receive messages.
|
|
Messages are comprised of signals. Signals and messages have attributes.
|
|
All of them can have comments.
