Adds all of the elements in the specified collection to this
queue. Attempts to addAll of a queue to itself result in
{@code IllegalArgumentException}. Further, the behavior of
this operation is undefined if the specified collection is
modified while the operation is in progress.
<p>This implementation iterates over the specified collection,
and adds each element returned by the iterator to this
queue, in turn. A runtime exception encountered while
trying to add an element (including, in particular, a
{@code null} element) may result in only some of the elements
having been successfully added when the associated exception is
thrown.
