CheckISpecSyntax(cls, ipolicy, name, check_std)
Class Method

source code

Check the instance policy for validity on a given key.

We check if the instance policy makes sense for a given key, that is if ipolicy[min][name] <= ipolicy[std][name] <= ipolicy[max][name].

Parameters:

ipolicy (dict) - dictionary with min, max, std specs
name (string) - what are the limits for
check_std (bool) - Whether to check std value or just assume compliance

Raises:

errors.ConfigureError - when specs for given name are not valid

CheckParameter(cls, key, value)
Class Method

source code

Checks a parameter.

Currently we expect all parameters to be float values.
