  - next
```
public BT next(BT reuse)
```
    Description copied from interface: MutableObjectIterator
    
    Gets the next element from the collection. The contents of that next element is put into the given reuse object, if the type is mutable.
    
    Specified by:
    
    next in interface MutableObjectIterator<BT>
    
    Parameters:
    
    reuse - The target object into which to place next element if E is mutable.
    
    Returns:
    
    The filled object or null if the iterator is exhausted.
  - next
```
public BT next()
```
    Description copied from interface: MutableObjectIterator
    
    Gets the next element from the collection. The iterator implementation must obtain a new instance.
    
    Specified by:
    
    next in interface MutableObjectIterator<BT>
    
    Returns:
    
    The object or null if the iterator is exhausted.
  - writeBack
```
public void writeBack(BT value)
               throws IOException
