|ABAP||The following keywords increase the complexity by one: |
AND, CATCH, CONTINUE, DO, ELSEIF, IF, LOOP, LOOPAT, OR, PROVIDE, SELECT…ENDSELECT, TRY, WHEN, WHILE
The complexity gets incremented by one for: function definitions,
for, throw statements,
return (except if it is the last statement of a function),
? ternary operator,
|Cobol||The following commands increase the complexity by one: |
ALSO, ALTER, AND, DEPENDING, END_OF_PAGE, ENTRY, EOP, EXCEPTION, EXIT, GOBACK, CONTINUE, IF, INVALID, OR, OVERFLOW, SIZE, STOP, TIMES, UNTIL, USE, VARYING, WHEN, EXEC CICS HANDLE, EXEC CICS LINK, EXEC CICS XCTL,
EXEC CICS RETURN
- Keywords incrementing the complexity:
return (that is not the last statement of a method),
finally keywords do not increment the complexity.
- a simple method with a switch statement and a huge block of case statements can have a surprisingly high complexity value (still it has the same value when converting a switch block to an equivalent sequence of if statements).
- accessors are not considered as methods and so do not increment the complexity
Example: the following method has a complexity of 5
|PL/I||The following keywords increase the complexity by one: |
PROC, PROCEDURE, GOTO, GO TO, RETURN, DO, IF, WHEN, |, !, |=, !=, &, &=
|PL/SQL||The complexity gets incremented by one for: the main PL/SQL anonymous block (not inner ones), create procedure, create trigger, procedure_definition, basic loop statement, when_clause_statement (the “when” of simple_case_statement and searched_case_statement), continue_statement, cursor_for_loop_statement, continue_exit_when_clause (The “WHEN” part of the continue and exit statements), exception_handler (every individual “WHEN”), exit_statement, for_loop_statement, forall_statement, if_statement, elsif_clause, raise_statement, return_statement, while_loop_statement, and_expression (“and” reserved word used within PL/SQL expressions), or_expression (“or” reserved word used within PL/SQL expressions), when_clause_expression (the “when” of simple_case_expression and searched_case_expression)|
|VB.NET||The complexity gets incremented by one for: method or constructor declaration (|
AndAlso, Case, Continue, End, Error, Exit, If, Loop, On Error, GoTo, OrElse, Resume, Return (except if it is the last statement of a function),
Stop, Throw, Try.
|Web||Complexity of the web page is measured by counting the decision tags (such as |
forEach) and boolean operators in expressions (
||), plus one for the body of the document. The decision tags and the operators are configurable through the Complexity rule.
