Class FacetArrays

java.lang.Object
  org.apache.lucene.facet.search.FacetArrays

Direct Known Subclasses:

ReusingFacetArrays

public class FacetArrays
extends Object

Provider of arrays used for facets aggregation. Returns either an int[] or float[] of the specified array length. When the arrays are no longer needed, you should call free(), so that e.g. they will be reclaimed.

NOTE: if you need to reuse the allocated arrays between search requests, use ReusingFacetArrays.

NOTE: this class is not thread safe. You typically allocate it per search.

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