Examples of java.util.concurrent.CopyOnWriteArrayList$ListIteratorImpl

java.util.concurrent.CopyOnWriteArrayList
list iterator implementation, when created gets snapshot of the list, so never throws ConcurrentModificationException


    private static<T extends ParamValidator> void addValidators (ConcurrentHashMap<Class, List<ParamValidator>> map, Class<T> clazz,
                                                                 T requiredValidator, T noneRequiredValidator) {


        // use <CopyOnWriteArrayList> in case validators are added while initializing parameters through <getValidator> method.
        List validators = new CopyOnWriteArrayList(new ParamValidator[]{requiredValidator, noneRequiredValidator});
        map.put(clazz, validators);
