KmfSystem

class canlib.kvmlib.KmfSystem(handle)[source]

The base class of Kmf and Memorator

The Kmf and Memorator classes are very similar, they are different ways of reading log files (LogFile) created by a memorator. This class represents the common ground between all ways of accessing log files.

All subclasses should have a log attribute which is an UnmountedLog or subclass thereof.

This class automatically closes its internal handle when garbage collected.
