| 28 | * Detects inline conditionals. | |
| 29 | * | |
| 30 | * <p>An example inline conditional is this: | |
| 31 | * <pre> | |
| 32 | * String a = getParameter("a"); | |
| 33 | * String b = (a==null || a.length<1) ? null : a.substring(1); | |
| 34 | * </pre> | |
| 35 | * Rationale: Some developers find inline conditionals hard to read, | |
| 36 | * so their company's coding standards forbids them. | |
