MergingIterator (htsjdk 2.18.2 API)

java.lang.Object
- htsjdk.samtools.util.MergingIterator<T>

All Implemented Interfaces:

CloseableIterator<T>, Closeable, AutoCloseable, Iterator<T>
```
public class MergingIterator<T>
extends Object
implements CloseableIterator<T>
```
An iterator over Iterators that return Ts. Calling next() returns the next T ordered according to Comparator provided at construction time. Importantly, the elements in the input Iterators must already be sorted according to the provided Comparator.
