- * @author Vladimir Turovets This class is used to create HashMap<String, T>
- * from the list of T objects. We suppose that
- * 1) T object contains field 'parmName' or getter 'getParmName()'.
- * The value of object.parmName or object.getParmName() is used as
- * a key in created hashMap.
- * 2) for all objects in the list 'parmName' or getter
- * 'getParmName().toString' has to be unique and not null.
- * This class has one function only:
- * HashMap<String, T> hashMap(List<T> list, String name) and returns
- * hash map created from list.
