CyclomaticComplexity
CyclomaticComplexity (30)
Complexity is determined by the number of decision points in a method plus one for the
method entry. The decision points are 'if', 'while', 'for', and 'case labels'. Generally,
1-4 is low complexity, 5-7 indicates moderate complexity, 8-10 is high complexity,
and 11+ is very high complexity.
This rule is defined by the following Java class:
net.sourceforge.pmd.rules.CyclomaticComplexity
Example:
// Cyclomatic Complexity = 12
public class Foo {
1 public void example() {
2 if (a == b) {
3 if (a1 == b1) {
fiddle();
4 } else if a2 == b2) {
fiddle();
} else {
fiddle();
}
5 } else if (c == d) {
6 while (c == d) {
fiddle();
}
7 } else if (e == f) {
8 for (int n = 0; n < h; n++) {
fiddle();
}
} else{
switch (z) {
9 case 1:
fiddle();
break;
10 case 2:
fiddle();
break;
11 case 3:
fiddle();
break;
12 default:
fiddle();
break;
}
}
}
}
This rule has the following properties:
