AI-generated Key Takeaways
- 
          UserListIteratoris an iterator for user lists.
- 
          It includes methods like hasNext()to check for more elements,next()to get the next user list, andtotalNumEntities()to see the total number of matched entities.
- 
          The totalNumEntities()method provides the count before considering any limits on entity reads.
Typical usage:
while (userListIterator.hasNext()) { var userList = userListIterator.next(); }
Methods:
| Member | Type | Description | 
|---|---|---|
| hasNext() | boolean | Returns trueif the iterator has more elements. | 
| next() | AdsApp.UserList | Returns the next UserList in the iterator. | 
| totalNumEntities() | int | Returns the total number of entities matched by the selector which generated this iterator. | 
hasNext()
  Returns true if the iterator has more elements.  Return values:
| Type | Description | 
|---|---|
| boolean | trueif the iterator has more elements. | 
next()
  Returns the next UserList in the iterator.  Return values:
| Type | Description | 
|---|---|
| AdsApp.UserList | The next UserList in the iterator. | 
totalNumEntities()
  Returns the total number of entities matched by the selector which
generated this iterator.
Note that the returned number disregards limits, and that the iterator
is not guaranteed to have this many elements — hasNext will
start to return false and next will start to
throw exceptions as soon as the limit for entity reads has been reached,
even if the selector matched more entities.  
Return values:
| Type | Description | 
|---|---|
| int | The number of entities matched by the selector which generated this iterator. |
