insertAll abstract method

void insertAll(int index, Iterable<E> iterable)

Inserts all objects of iterable at position index in this list.

This increases the length of the list by the length of iterable and shifts all later objects towards the end of the list.

An error occurs if the index is less than 0 or greater than length. An UnsupportedError occurs if the list is fixed-length.
