| 25 | * Checks cyclomatic complexity against a specified limit. The complexity is | |
| 26 | * measured by the number of "if", "while", "do", "for", "?:", "catch", | |
| 27 | * "switch", "case", "&&" and "||" statements (plus one) in the body of | |
| 28 | * the member. It is a measure of the minimum number of possible paths through | |
| 29 | * the source and therefore the number of required tests. Generally 1-4 is | |
| 30 | * considered good, 5-7 ok, 8-10 consider re-factoring, and 11+ re-factor now! | |
