```
public FlatIterator(Iterable<?> iterable)
```
    Parameters:
    
    iterable - Input iterable of iterators.
- Method Detail
  - hasNextX
```
public boolean hasNextX()
```
    This method is the same as Iterator.hasNext(), but allows for failure with exception. Often iterators are used to iterate through values that have not or have partially been received from remote nodes, and need to account for possible network failures, rather than just returning false out of Iterator.hasNext() method.
    
    Returns:
    
    True if iterator contains more elements.

    Iterator.hasNext()
  - nextX
```
public T nextX()
```
    This method is the same as Iterator.next(), but allows for failure with exception. Often iterators are used to iterate through values that have not or have partially been received from remote nodes, and need to account for possible network failures, rather than throwing NoSuchElementException runtime exception.s
    
    Returns:
    
    True if iterator contains more elements.
