## Class DisiPriorityQueue

- java.lang.Object
- - org.apache.lucene.search.DisiPriorityQueue

- All Implemented Interfaces:
    Iterable<DisiWrapper>

      public final class DisiPriorityQueue
      extends Object
      implements Iterable<DisiWrapper>

  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.
