Check

class component_model.variable.Check(value, names=_not_given, *values, module=None, qualname=None, type=None, start=1, boundary=None)

Bases: IntFlag

Flags to denote how variables should be checked with respect to units and range. The aspects are indepent, but can be combined in the Enum through | or &.

• none: neither units nor ranges are expected or checked.

• unitNone: only numbers without units expected when new values are provided. If units are provided during initialization, these should be base units (SE), i.e. unit and display are the same.

• u_all: expect always quantity and number and convert internally to base units (SE). Provide output as display

• units: flag to filter only on units, e.g ck & Check.units

• r_none: no range is provided or checked

• r_check: range is provided and checked

• ranges: flag to filter on range, e.g. ck & Check.ranges

• all: short for u_all | r_check

Methods

conjugate	Returns self, the complex conjugate of any int.
bit_length()	Number of bits necessary to represent self in binary.
bit_count()	Number of ones in the binary representation of the absolute value of self.
to_bytes([length, byteorder, signed])	Return an array of bytes representing an integer.
from_bytes([byteorder, signed])	Return the integer represented by the given array of bytes.
as_integer_ratio()	Return a pair of integers, whose ratio is equal to the original int.
is_integer()	Returns True.
