Lets say i have an Array collection, filled with some elements. If i say
myArrayCollection.addItemAt(object,0);
What exactly happens here? Does all the elements gets shifted rigthwards? or element at 0th position gets replaced with new one?
To summarize, the reason there are two different methods, addItemAt() and setItemAt(), is because one of them adds a new item (not replacing any of the existing ones), and the other sets/overwrites the existing index.
For more info, check out the ArrayCollection documentation.
