- Method Detail
  - next
```
Molecule next()
```
    Gets the next molecule.
    
    Specified by:
    
    next in interface Iterator<Molecule>
    
    Returns:
    
    the molecule or null at end of file
    
    Throws:
    
    NoSuchElementException - if an error occurred, and the next element cannot be returned
  - hasNext
```
boolean hasNext()
```
    Tests whether the iteration has more elements.
    
    Specified by:
    
    hasNext in interface Iterator<Molecule>
    
    Returns:
    
    true if the iterator has more elements, false if there are no more elements
  - getThrowable
```
@Deprecated
Throwable getThrowable()
```
    Deprecated.
    Not used. next() throws NoSuchElementException in case of error.
    
    Gets the exception which stopped the iteration. It should be called when hasNext() returns false.
    
    Returns:
    
    the exception if the iteration was stopped by an error, null if it stopped normally
  - estimateProgress
```
double estimateProgress()
```
    Estimates the iteration progress.
    
    Returns:
    
    number between 0 and 1
