SortedView (datasketches-java 6.1.0 API)

```
public interface SortedView
```
This is the base interface for the Sorted View interface hierarchy and defines the methods that are type independent.
The SortedView interface hierarchy provides a sorted view of the data retained by a quantiles-type sketch that would be cumbersome to get any other way. One could use the sketch's iterator to iterate over the contents of the sketch, but the result would not be sorted.

The data from a Sorted view is an unbiased random sample of the input stream that can be used for other kinds of analysis not directly provided by the sketch.

- Method Detail
  - getCumulativeWeights
```
long[] getCumulativeWeights()
```
    Returns the array of cumulative weights from the sketch. Also known as the natural ranks, which are the Natural Numbers on the interval [1, N].
    
    Returns:
    
    the array of cumulative weights (or natural ranks).
  - getN
```
long getN()
```
    Returns the total number of items presented to the sourcing sketch.
    
    Returns:
    
    the total number of items presented to the sourcing sketch.
  - getNumRetained
```
int getNumRetained()
```
    Gets the number of quantiles retained by this sorted view. This may be slightly different from the function with the same name when called from the originating sketch.
    
    Returns:
    
    the number of quantiles retained by this sorted view
  - isEmpty
```
boolean isEmpty()
```
    Returns true if this sorted view is empty.
    
    Returns:
    
    true if this sorted view is empty.
  - iterator
```
SortedViewIterator iterator()
```
    Returns an iterator for this Sorted View.
    
    Returns:
    
    an iterator for this Sorted View.
