void addAll(Collection dest, Iterator src)
add All

if (src != null) {
 while (src.hasNext()) {
 T value = src.next();
 dest.add(value);

C addAll(final C collection, final Iterator iter)
adds all elements from iter to collection

while (iter.hasNext()) {
 collection.add(iter.next());
return collection;

void addAll(final Collection targetCollection, final Iterator sourceIterator)
Adds all elements that a given Iterator provides to a given Collection of appropriate type

while (sourceIterator.hasNext()) {
 targetCollection.add(sourceIterator.next());

void addAll(Iterator iteratorFrom, Collection collectionTo)
If the given Iterator is not null, iterate over all T elements in it and add them to the given Collection.

if (iteratorFrom != null) {
 while (iteratorFrom.hasNext()) {
 collectionTo.add(iteratorFrom.next());

U addAll(Iterator source, U target)

while (source.hasNext()) {
 target.add(source.next());
return target; 

List addAll(List target, Iterator source)
add All

if (source == null)
 return target;
for (; source.hasNext(); target.add(source.next()))
 ;
return target;

 s.add(i.next());

COLL addAllFromIterator(COLL dest, Iterator source)

while (source.hasNext()) {
 dest.add(source.next());
return dest;

LinkedList addAllToList(Iterator i)
Adds all elements of iterator's range to a new linked list.

LinkedList<T> result = new LinkedList<T>();
while (i.hasNext()) {
 result.add(i.next());
