Number of Executable Lines

Number of executable lines in function body

Description

This metric measures the number of executable lines in a function body. When calculating the value of this metric, Polyspace® excludes declarations, comments, blank lines, braces or preprocessing directives.

If the function body contains a #include directive, the included file source code is also calculated as part of this metric.

This metric is not calculated for C++ function templates and lambdas. For these entities, the value is reported as Not computed.

void func(int, double);

	int getSign(int arg) {//Excluded
	int sign; //Excluded
	static int siNumber = 0; //Excluded
	double dNumber = 5;//Excluded
	if(arg<0) {
		sign=-1;
		func(-arg,dNumber);
		++siNumber;
		/* func takes positive first argument */   //Excluded
	}//Excluded
	else if(arg==0)
	sign=0;
	else {
		sign=1;
		func(arg,dNumber);
		++siNumber;
	}//Excluded
	return sign;
}//Excluded

In this example, the number of executable lines of getSign is 11. The calculation excludes:

  • The definition of the function.

  • The variable declarations.

  • The comment /* ... */.

  • The lines with braces only.
