Attributes
- allow_none
If True, None is allowed as a valid value.
allow_none = Bool(True)
- family_trait
When set, the name of the units family_name trait that the units value must be compatible with.
family_trait = Str
- is_strict
If True, attempts to assign values that cannot be parsed raise exceptions. If False, values that cannot be parsed default to 'dimensionless'.
is_strict = Bool(False)

Methods
- info(self)
Returns message substring.
- validate(self, obj, name, value)
Requires that value be either a valid units expression or units object. If not, the value 'dimensionless' is assumed. The returned value, and thus the value of a units trait will alawys be the unit object.
