CyclomaticComplexity


CyclomaticComplexity
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;
            }
        }
    }
}
