Confiurations

Configuration

class canlib.kvamemolibxml.Configuration(xml=None, lif=None)

Configuration data for Kvaser devices

It is usually preferred to create objects of this class with one of the functions:

• load_xml

• load_xml_file

• load_lif

• load_lif_file

The XML and param.lif representation of this configuration can be accessed with the xml and lif attributes, respectively.

Two Configuration objects can be tested for equality:

config1 == config2

This will test whether the objects are equivalent: whether they have the same param.lif representation.

Finally, the configuration can be validated with Configuration.validate:

errors, warnings = configuration.validate()
for error in errors:
    print(error)
for warning in warnings:
    print(warning)
if errors:
    raise ValueError("Invalid configuration")

property lif

The param.lif representation of this configuration

Type

bytes

validate()

Validate this configuration

Validates the XML representation of this configuration, and returns a tuple (errors, warnings) where errors is a list of ValidationError and warnings is a list ValidationWarning.

property xml

The XML representation of this configuration

Type

str

load_lif()

canlib.kvamemolibxml.load_lif(lif_bytes)

Create a Configuration from a param.lif bytes

Parameters

lif_bytes (bytes) – Binary configuration in param.lif format

load_lif_file()

canlib.kvamemolibxml.load_lif_file(filepath)

Like load_lif but takes a path to a file containing the lif configuration

load_xml()

canlib.kvamemolibxml.load_xml(xml_string)

Create a Configuration from an xml string

Parameters

xml_string (str) – XML configuration

load_xml_file()

canlib.kvamemolibxml.load_xml_file(filepath)

Like load_lif but takes a path to a file containing the XML configuration
