MergeSortedIterators (Oak DocumentNodeStore 1.22.9 API)

java.lang.Object
- org.apache.jackrabbit.oak.plugins.document.util.MergeSortedIterators<T>

Type Parameters:

T - the entry type

All Implemented Interfaces:

Iterator<T>
```
public abstract class MergeSortedIterators<T>
extends Object
implements Iterator<T>
```
MergeSortedIterators is a specialized implementation of a merge sort of already sorted iterators of some type of comparable elements. The input iterators must return the elements in sorted order according to the provided Comparator. In addition the sequence of iterators must also be sorted in a way that the first element of the next iterator is greater than the first element of the previous iterator.
