qudi.util.descriptors.TypedAttribute

class qudi.util.descriptors.TypedAttribute(valid_types: ~typing.Iterable[~typing.Type] | None = None, default: ~typing.Any | None = <object object>)

Bases: qudi.util.descriptors.TypedMixin, qudi.util.descriptors.DefaultAttribute

Extension of DefaultAttribute including type checking via isinstance. A given default value is not type-checked.

Example usage:

class Test:

variable_a = TypedAttribute([int, float]) variable_b = TypedAttribute([str], None) def __init__(self):

assert self.variable_b is None self.variable_a = 42 self.variable_b = ‘hello world’ assert self.variable_a == 42 assert self.variable_b == ‘hello world’ # The following would raise TypeError # self.variable_a = self.variable_b = None

__init__(valid_types: ~typing.Iterable[~typing.Type] | None = None, default: ~typing.Any | None = <object object>)

Methods

__init__([valid_types, default])
check_type(value)

check_type(value: Any) → None
