LazyIterableIterator (Apache SystemDS 3.3.0 API)

java.lang.Object
- org.apache.sysds.runtime.instructions.spark.data.LazyIterableIterator<T>

All Implemented Interfaces:

Iterable<T>, Iterator<T>
```
public abstract class LazyIterableIterator<T>
extends Object
implements Iterable<T>, Iterator<T>
```
This class is a generic base class for lazy, single pass iterator classes in order to simplify the implementation of lazy iterators for mapPartitions use cases. Note [SPARK-3369], which gives the reasons for backwards compatibility with regard to the iterable API despite Spark's single pass nature.
