TupleUnwrappingIterator (Flink : Java 1.20.1-cp2 API)

java.lang.Object
- org.apache.flink.api.java.operators.translation.TupleUnwrappingIterator<T,K>

All Implemented Interfaces:

Serializable, Iterable<T>, Iterator<T>
```
@Internal
public class TupleUnwrappingIterator<T,K>
extends Object
implements Iterator<T>, Iterable<T>, Serializable
```
An iterator that reads 2-tuples (key value pairs) and returns only the values (second field). The iterator also tracks the keys, as the pairs flow though it.
