Annotation Type UtilityClass


  • @Target(TYPE)
    @Retention(SOURCE)
    public @interface UtilityClass
    An annotation to create utility classes. If a class is annotated with @UtilityClass, the following things happen to it:
    • It is marked final.
    • If any constructors are declared in it, an error is generated. Otherwise, a private no-args constructor is generated; it throws a UnsupportedOperationException.
    • All methods, inner classes, and fields in the class are marked static.
    • WARNING: Do not use non-star static imports to import these members; javac won't be able to figure it out. Use either: import static ThisType.*; or don't static-import.
