```
  - count
```
public static int count(CloseableIterator<?> it)
                 throws IteratorException
```
    Throws:
    
    IteratorException
  - count
```
public static int count(CloseableIteratorWithoutException<?> it)

```
public static <T> CloseableIterator<T> uniqLocaly(CloseableIterator<T> it)
```
    Remove adjacent equals elements.
    
    Parameters:
    
    it -
    
    Returns:
    
    a CloseableIterator.
  - sort
```
public static <T extends Comparable<T>> CloseableIterator<T> sort(CloseableIterator<T> it)
