BoolAttribute

class dtaianomaly.type_validation.BoolAttribute[source]

Validator for booleans.

Check if the given value is a boolean.

Examples

>>> from dtaianomaly.type_validation import BoolAttribute
>>> a_bool = BoolAttribute()
>>> a_bool.raise_error_if_invalid(True, "my_attribute", "MyClass")   # No error
>>> a_bool.raise_error_if_invalid(False, "my_attribute", "MyClass")  # No error
>>> a_bool.raise_error_if_invalid("not-a-bool", "my_attribute", "MyClass")
Traceback (most recent call last):
    ...
TypeError: Attribute 'my_attribute' in class 'MyClass' must be of type bool, but received 'not-a-bool' of type <class 'str'>!

raise_error_if_invalid(value, name: str, class_name: str) → None

Raise an error if the given value is invalid.

Check if the type and the exact value are permitted, according to the rules of this attribute validation. If either the type or the value is invalid, an error is raised accordingly. Otherwise, nothing happens.

Parameters:

valueany: The value to verify.
namestr: The name of the attribute that is being checked. Used for generating clear error messages, if needed.
class_namestr: The name of the class to which the attribute belongs. Used for generating clear error messages, if needed.

Raises:

TypeError: If the type of the given value is invalid according to the rules of this BaseAttributeValidation.
ValueError: If the value of the given value is invalid according to the rules of this BaseAttributeValidation.
