AntiPatternRules_Arnaoudova.md

Linguistic anti-patterns, defined by Arnaoudova et al [1].

Id	Name	Definition	Python File
A.1	Get more than accessor	A getter that performs actions other than returning the corresponding attribute.	get_more_than_accessor.py
A.2	Is returns more than a Boolean	The name of a method is a predicate suggesting a true/false value in return. However the return type is not Boolean but rather a more complex type.	is_no_return_bool.py
A.3	Set method returns	A set method having a return type different than void.	set_returns.py
A.4	Expecting but not getting single instance	The name of a method indicates that a single object is returned but the return type is a collection.	expecting_not_getting_single.py
B.1	Not implemented condition	The comments of a method suggest a conditional behavior that is not implemented in the code. When the implementation is default this should be documented	not_implemented_condition.py
B.2	Validation method does not confirm	A validation method (e.g., name starting with validate, check, ensure) does not confirm the validation, i.e., the method neither provides a return value informing whether the validation was successful, nor documents how to proceed to understand.	validate_not_confirm.py
B.3	Get method does not return	The name suggests that the method returns something (e.g., name starts with get or return) but the return type is void.	get_no_return.py
B.4	Not answered question	The name of a method is in the form of predicate whereas the return type is not Boolean.	not_answered_question.py
B.5	Transform method does not return	The name of a method suggests the transformation of an object but there is no return value and it is not clear from the documentation where the result is stored.	transform_not_return.py
B.6	Expecting but not getting a collection	The name of a method suggests that a collection should be returned but a single object or nothing is returned.	expecting_not_getting_collection.py
C.1	Method name and return type are opposite	The documentation of a method is in contradiction with its declaration.	method_name_return_opposite.py
C.2	Method signature and comment are opposite	The name of an attribute suggests a single instance, while its type suggests that the attribute stores a collection of objects.	method_signature_comment_opposite.py
D.1	Says one but contains many	The name of an attribute suggests a single instance, while its type suggests that the attribute stores a collection of objects.	says_one_contains_many.py
D.2	Name suggests boolean but type is not	The name of an attribute suggests that its value is true or false, but its declaring type is not Boolean.	name_suggest_boolean_type_not.py
E.1	Says many but contains one	The name of an attribute suggests multiple instances, but its type suggests a single one.	says_many_contains_one.py
F.1	Attribute name and type are opposite	The name of an attribute is in contradiction with its type as they contain antonyms.	attribute_name_type_opposite.py
F.2	Attribute signature and comment are opposite	The declaration of an attribute is in contradiction with its documentation.	attribute_signature_comment_opposite.py
