Interface LuceneSliceQueue.LeafSplitGuard

Enclosing class:
LuceneSliceQueue
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public static interface LuceneSliceQueue.LeafSplitGuard
Per-leaf hint that suppresses sub-segment splitting for the LuceneSliceQueue.PartitioningStrategy.DOC partitioner.

Used by LuceneCountOperator, which probes Weight.count(LeafReaderContext) per leaf and keeps shortcut-eligible leaves whole so the leaf-wide count can fire via LuceneOperator.LuceneScorer.coversFullLeaf() instead of being iterated by the BulkScorer.
