Annotation Type I18nFormatFor


  • @Documented
    @Retention(RUNTIME)
    @Target({TYPE_USE,TYPE_PARAMETER})
    @SubtypeOf(I18nUnknownFormat.class)
    public @interface I18nFormatFor
    This annotation indicates that when a string of the annotated type is passed as the first argument to MessageFormat.format(String, Object...), then the expression that is an argument to the annotation can be passed as the remaining arguments, in varargs style.

    The annotation is used to annotate a method to ensure that an argument is of a particular type indicated by a format string.

    Example:

     static void method(@I18nFormatFor("#2") String format, Object... arg2) {...}
    
     method("{0, number}", 2);
    This ensures that the second parameter ("#2") can be passed as the remaining arguments of MessageFormat.format(String, Object...), when the first argument is "format".
