Kmf¶

class canlib.kvmlib.Kmf(handle, ldf_version)[source]¶

A kmf file opened with kvmlib.openKmf

The main use of this class is using its log attribute, which is a MountedLog object (see its documentation for how to use it).

Also see the base class kvmlib.KmfSystem for inherited functionality.

Variables: log (MountedLog) – Object representing the log of log files within the kmf container-file.

New in version 1.6.

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.

New in version 1.6.

class DiskUsage(used, total)¶

property total¶: Alias for field number 1

property used¶: Alias for field number 0

close()[source]¶: Close the internal handle

Warning

This invalidates the object.

property disk_usage¶

The disk usage

The tuple has one used and one total field (in that order), which reference disk space in megabytes.

Type: KmfSystem.DiskUsage
