@Deprecated public abstract class IntTaxonomyFacets extends TaxonomyFacets
Deprecated.Visibility of this class will be reduced to pkg-private in a future version. This class is meant to host common code as an internal implementation detail toFastTaxonomyFacetCounts
andTaxonomyFacetIntAssociations
,and is not intended as an extension point for user-createdFacets
implementations. If your code is relying on this, please migrate necessary functionality down into your own class.Base class for all taxonomy-based facets that aggregate to a per-ords int[].

aggregationFunction
protected final AssociationAggregationFunction aggregationFunction
Deprecated.Aggregation function used for combining values.
-
values
protected final int[] values
Deprecated.Dense ordinal values.We are making this and
sparseValues
protected for some expert usage. e.g. It can be checked which is being used before a loop instead of callingincrement(int)
for each iteration.
-
sparseValues
protected final com.carrotsearch.hppc.IntIntHashMap sparseValues
Deprecated.Sparse ordinal values.- See Also:
for why protected.

getSpecificValue
public Number getSpecificValue(String dim, String... path) throws IOException
Deprecated.Description copied from class:Facets
Return the count or value for a specific path. Returns -1 if this path doesn't exist, else the count.- Specified by:
getSpecificValue
in classFacets
- Throws:
IOException
-
getAllChildren
public FacetResult getAllChildren(String dim, String... path) throws IOException
Deprecated.Description copied from class:Facets
Returns all child labels with non-zero counts under the specified path. Users should make no assumptions about ordering of the children. Returns null if the specified path doesn't exist or if this dimension was never seen.- Specified by:
getAllChildren
in classFacets
- Throws:
IOException
-
getTopChildren
public FacetResult getTopChildren(int topN, String dim, String... path) throws IOException
Deprecated.Description copied from class:Facets
Returns the topN child labels under the specified path. Returns null if the specified path doesn't exist or if this dimension was never seen.- Specified by:
getTopChildren
in classFacets
- Throws:
IOException
-
getTopDims
public List<FacetResult> getTopDims(int topNDims, int topNChildren) throws IOException
Deprecated.Description copied from class:Facets
Returns labels for topN dimensions and their topNChildren sorted by the number of hits/aggregated values that dimension matched. Results should be the same as calling getAllDims and then only using the first topNDims. Note that dims should be configured as requiring dim counts if using this functionality to ensure accurate counts are available (see:FacetsConfig.setRequireDimCount(String, boolean)
).Sub-classes may want to override this implementation with a more efficient one if they are able.

getTopDims
