Cyclomatic complexity in CodeScan is calculated by the number of decision points in a method.
For example, the below method would have a cyclomatic complexity of 5.
public void newMethod() {
for(Integer i = 0; i < 100; i++){
if (a == b && b == c){
doStuff();
} else if(a != b) {
doOtherStuff();
}
}
}
This counts:
- The entry to the method
- The entry to the for loop
- The if statement and the first conditional
- The second conditional in the if statement
- The elseif statement
This does not include:
- else statements
- when else in switch statements
The cyclomatic complexity for a class will be the average complexity between all methods in that class.
