27 | * <p> | |
28 | * Detects empty statements (standalone ';'). | |
29 | * Empty statements often introduce bugs | |
30 | * that are hard to spot, such as in | |
31 | * </p> | |
32 | * <pre> | |
33 | * if (someCondition); | |
34 | * doConditionalStuff(); | |
35 | * doUnconditionalStuff(); | |
36 | * </pre> | |
37 | * <p> | |
38 | * An example of how to configure the check is: | |
