| 24 | /** | |
| 25 | * <p> | |
| 26 | * Checks that switch statement has "default" clause. | |
| 27 | * </p> | |
| 28 | * <p> | |
| 29 | * Rationale: It's usually a good idea to introduce a | |
| 30 | * default case in every switch statement. Even if | |
| 31 | * the developer is sure that all currently possible | |
| 32 | * cases are covered, this should be expressed in the | |
| 33 | * default branch, e.g. by using an assertion. This way | |
| 34 | * the code is protected aginst later changes, e.g. | |
| 35 | * introduction of new types in an enumeration type. | |
| 36 | * </p> | |
| 37 | * <p> | |
| 38 | * An example of how to configure the check is: | |
| 39 | * </p> | |
