All Implemented Interfaces:

```
public class DistinctDataNet<E>
extends DistinctDataBag<E>
```
This class is like DistinctDataBag except that you are informed if the item you just added was known to be distinct. This will normally only work until the first spill. After that, the system may not be able to tell for sure, and will thus return false. When you are finished adding items, you may call netIterator() to get any distinct items that are in the spill files but were not indicated as distinct previously.

public DistinctDataNet(ThresholdPolicy<E> policy,
                       SerializationFactory<E> serializerFactory,
                       java.util.Comparator<E> comparator)
```
- Method Detail
  - netAdd
```
public boolean netAdd(E item)
```
    Returns:
    
    true if the item added is known to be distinct.
  - netIterator
```
public java.util.Iterator<E> netIterator()
```
    Returns an iterator to all additional items that are distinct but were not reported to be so at the time netAdd(Object) was invoked.
    If you do not exhaust the iterator, you should call Iter.close(Iterator) to be sure any open file handles are closed.
