Class DisiPriorityQueue<Iter extends DocIdSetIterator>

java.lang.Object

org.apache.lucene.search.DisiPriorityQueue<Iter>

All Implemented Interfaces:

Iterable<DisiWrapper<Iter>>

public final class DisiPriorityQueue<Iter extends DocIdSetIterator>
extends Object
implements Iterable<DisiWrapper<Iter>>

A priority queue of DocIdSetIterators that orders by current doc ID. This specialization is needed over PriorityQueue because the pluggable comparison function makes the rebalancing quite slow.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.
