LeafFacetCutter (Lucene 10.5.1 sandbox API)
Description: declaration: package: org.apache.lucene.sandbox.facet.cutters, interface: LeafFacetCutter

Package org.apache.lucene.sandbox.facet.cutters

# Interface LeafFacetCutter

All Superinterfaces:
  `OrdinalIterator`

public interface LeafFacetCutter extends OrdinalIterator
Interface to be implemented to cut documents into facets for an index segment (leaf).

When `advanceExact(int)` returns true, `OrdinalIterator.nextOrd()` yields all facet ordinals for the current document. It is illegal to call `OrdinalIterator.nextOrd()` if `advanceExact(int)` returns false.

WARNING: This API is experimental and might change in incompatible ways in the next release.
