Name	Description	Metric code	ID	Languages
Lines of code	number of lines of code in the method or function; calculated as (last line number) - (first line number) + 1	LOC_METHOD	129	C/C++, Java
Number of operands used	An operand is an identifier or a constant. This metric calculates the total number of identifiers and constants used in the function or method. Note that a method name is also an identifier. For this metric, a function call is considered an operator.	NOOPUSED	130	C/C++, Java
Number of distinct operands used	number of unique operands (variables and constants) used in the current function. Variables are distinguished by name, so usages of overridden variables do not contribute to this metric. Constants are distinguished by value, so all strings are assumed to be unique. For this metric, a function call is considered an operator.	NODISOPUSED	131	C/C++, Java
Number of operators used	number of operators used in the function or method. This metric counts the total number of accesses to variable, binary, ternary, unary, field access, index access, call, new instance of, expr-class, expression-this, and expression-super. All function calls are considered as operators.	NOOPRUSED	132	C/C++, Java
Number of distinct operators used	number of unique operators used in the function. Like NOOPRUSED, but function calls are considered as one unique operator. For example, Msg and printf function calls are counted only once.	NODISOPRUSED	133	C/C++, Java
Number of returns	number of return statements in the function (not return points)	NORET	134	C/C++, Java
Cyclomatic complexity	cyclomatic complexity (McCabe Cyclomatic Complexity metric) shows the number of areas plane is divided by control flow graph	CYCLOMATIC	135	C/C++, C#, Java
Number of independent paths	the output value is (log_e) (number of paths within function/method). All loops and if-statements are considered as two independent paths. Goto statements in C++ are not taken into consideration in this calculation. Each catch clause is an independent path.	NOINDPATHS	136	C/C++, Java
Number of parameters	number of parameters (arguments) in the function or method. In this example f(x,y+z, foo (g)) x, y+z, and g are parameters passed to other functions so the number would be 3.	NOPARMS	137	C/C++, C#, Java
Number of calls to unique functions	the number of calls from function or methods (for which metrics are calculated) to other functions or methods. Any number of calls to the same function or method adds only one to this metric.	NOCALLS	138	C/C++, Java
Number of calls outside the class	number of calls outside the class (number of calls to methods with different "this"): For a method, this metric is equal to the total number of calls minus the number of calls to other methods of the same class (including self). For a function that is not a method, this metric is equal to the total number of calls.	NOCALLSOC	139	C/C++, Java
Number of parameters passed to other functions	number of parameters passed to other functions. In this example, foo (int i) { bar (1, 2, 3); 700 (1); } the number is 4	NOPAROTHER	140	C/C++, Java
Number of executable statements	number of executable and blank statements in the function or method. An executable statement is an operator such as a+=b; or a function call such as f(s+y, z).	NOEXSTAT	141	C/C++, Java
Number of statements	number of expression and control statements (if, for, while). This metric is the sum of NOCONTROLSTAT, NOEXSTAT, and NOMDECLSTAT for the function or method.	NOSTAT	142	C/C++, Java
Number of loops	number of for, while, and do-while statements in the current function	NOLOOPS	143	C/C++, Java
Number of conditional statements	number of if and switch statements in the current function	NOIF	144	C/C++, Java
Number of else and case statements	number of else and case statements in the current function. Default statements are not included.	NOBRANCH	145	C/C++, Java
Maximum level of control nesting	maximum level of nested control statements (if, switch, for, while, and do-while statements). The initial MAXLEVEL (for example, a function with no operators) is equal to 1.	MAXLEVEL	146	C/C++, C#, Java
Average level of control nesting	average number of executable statements in a function or method; calculated as the sum of the level of each executable statement for all statements in the function divided by the number of executable statements. If the number of executable statements is 0, AVERLEVEL is 0.	AVERLEVEL	147	C/C++, Java
Number of local declarations	number of data items declared locally within the function	NOLOCDECL	148	C/C++, Java
Maximum number of executable statements in a conditional arc	maximum number of executable statements located within the span of a branch of a conditional arc	MAXCONDSPAN	149	C/C++, Java
Number of conditional arcs in the control graph of the function or method	number of conditional branches in the control graph of the function or method (if, switch, do, while, or for statements)	NOCONDARCS	150	C/C++, Java
Number of control statements in the function or method	number of control statements (statements that operated control flow within a function or method). This metric calculates the number of loops or conditional statements (if, switch, do, while, for), plus the number of control-passing statements (return, break, continue, goto), plus the number of try-catch statements.	NOCONTROLSTAT	151	C/C++, Java
Number of declarative statements in the function or method	number of declarative statements in the function or method; for example, the declaration of a local array or a local variable. This differs from NOLOCDECL because 1 declaration statement can declare several local variables.	NOMDECLSTAT	152	C/C++, Java
Number of accesses to global variables	number of accesses (reads/writes) to variables defined outside the function or method	NOACCTOGLOB	153	C/C++, Java
Bytes of local variables declared	For more information about calculating this metric, see Specifying sizes for built-in types.	BYTESLOCDECL	154	C/C++
Bytes of parameters for the function	For more information about calculating this metric, see Specifying sizes for built-in types.	BYTESPARMS	155	C/C++
Bytes of parameters passed to other functions	For more information about calculating this metric, see Specifying sizes for built-in types.	BYTESPAROTHER	156	C/C++
Number of calls to non-prototyped functions	number of calls to non-prototyped functions. This metric depends on the completeness of the code. If code is compiled without includes, the metric would be only the number of calls (because no functions would be prototyped).	NOCALLSNP	159	C/C++
Number of reads from global variables	Number of reads from global variables	READFGLOBAL	160	C/C++, Java
Number of writes to global variables	Number of writes to global variables	WRITETGLOBAL	161	C/C++, Java
Non-comment, non-blank lines of code in the function or method	the number of lines of code in a function or method, not including comment lines and blank lines	NCNBLOC_METHOD	162	C/C++, C#, Java
Extended cyclomatic complexity	Extended cyclomatic complexity includes logical Boolean operators in the decision count. Whenever Klocwork finds a logical Boolean operator (&& or \|) within a conditional statement, EXTCYCLOMATIC increases by one. The conditionals Klocwork considers are: If, IfElse, While, DoWhile, For and Switch.	EXTCYCLOMATIC	164	C/C++
Plain cyclomatic complexity	Like Cyclomatic complexity (metric code 135), but is calculated on plain code (before preprocessor expansion). Any conditional statements generated from macro definitions do not result in PLAINCYCLOMATIC metric.	PLAINCYCLOMATIC	165	C/C++
Plain extended cyclomatic complexity	Like Extended cyclomatic complexity (metric code 164), but is calculated on plain code (before preprocessor expansion). Any conditional statements generated from macro definitions do not result in PLAINEXTCYCLOMATIC metric.	PLAINEXTCYCLOMATIC	166	C/C++
