spring modelandview object

[neil johnson]

modelandview has two methods
ModelAndView addAllObjects(Map modelMap)
Add all entries contained in the provided map to the model.
ModelAndView addObject(String modelName, Object modelObject)
Add an object to the model.


i am confused by having two methods. we can use addObject() in place of addAllObjects(). right? if not please clarify how addAllObjects() is useful.

It's useful if you want to add all items in the map, as opposed to doing it one at a time.

Just like how java.util.List has add and addAll.
