TaxonomyFacets
@Deprecated protected TaxonomyFacets(String indexFieldName, TaxonomyReader taxoReader, FacetsConfig config) throws IOException Deprecated.To be removed in Lucene 10.Constructor without aFacetsCollector
- we don't have access to the hits, so we have to assume there are hits when initializing internal data structures.- Throws:
IOException

Method Details
-
useHashTable
Deprecated.Return true if a sparse hash table should be used for counting, instead of a dense int[]. -
initializeValueCounters
protected void initializeValueCounters()Deprecated.If not done already, initialize the data structures storing counts. -
setCount
protected void setCount(int ordinal, int newValue) Deprecated.Set the count for this ordinal tonewValue
. -
getCount
protected int getCount(int ordinal) Deprecated.Get the count for this ordinal. -
getAggregationValue
Deprecated.Get the aggregation value for this ordinal. -
aggregate
Deprecated.Apply an aggregation to the two values and return the result. -
childrenLoaded
public boolean childrenLoaded()Deprecated.Returns true if the (costly, and lazily initialized) children int[] was initialized.- WARNING: This API is experimental and might change in incompatible ways in the next release.
-
siblingsLoaded
public boolean siblingsLoaded()Deprecated.Returns true if the (costly, and lazily initialized) sibling int[] was initialized.- WARNING: This API is experimental and might change in incompatible ways in the next release.
-
verifyDim
Deprecated.Verifies and returnsFacetsConfig.DimConfig
for the given dimension name.- Returns:
FacetsConfig.DimConfig
for the given dim, orFacetsConfig.DEFAULT_DIM_CONFIG
if it was never manually configured.- Throws:
IllegalArgumentException
- if the provided dimension was manually configured, but itsFacetsConfig.DimConfig.indexFieldName
does not matchindexFieldName
.
-
updateValueFromRollup
Deprecated.Roll-up the aggregation values fromchildOrdinal
toordinal
. Overrides should probably call this to update the counts. Overriding allows us to work with primitive types for the aggregation values, keeping aggregation efficient.- Throws:
IOException
-
makeTopOrdAndNumberQueue
Deprecated.Return aTopOrdAndNumberQueue
of the appropriate type, i.e. aTopOrdAndIntNumberQueue
or aTopOrdAndFloatNumberQueue
. -
missingAggregationValue
Deprecated.Return the value for a missing aggregation, i.e.-1
or-1f
. -
rollup
Deprecated.Rolls up any single-valued hierarchical dimensions.- Throws:
IOException
-
getAllChildren
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
-
setIncomingValue
Deprecated.Set the value for aTopOrdAndNumberQueue.OrdAndValue
to the one corresponding to the given ordinal. -
insertIntoQueue
protected TopOrdAndNumberQueue.OrdAndValue insertIntoQueue(TopOrdAndNumberQueue q, TopOrdAndNumberQueue.OrdAndValue incomingOrdAndValue, int ord) Deprecated.Insert an ordinal and the value corresponding to it into the queue. -
newAggregatedValue
Deprecated.Initialize an accumulator. -
getTopChildrenForPath
protected org.apache.lucene.facet.taxonomy.TaxonomyFacets.TopChildrenForPath getTopChildrenForPath(FacetsConfig.DimConfig dimConfig, int pathOrd, int topN) throws IOException Deprecated.Determine the top-n children for a specified dimension + path. Results are in an intermediate form.- Throws:
IOException
-
getTopChildren
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
-
getSpecificValue
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
-
getAllDims
Deprecated.Description copied from class:Facets
Returns topN labels for any dimension that had hits, sorted by the number of hits that dimension matched; this is used for "sparse" faceting, where many different dimensions were indexed, for example depending on the type of document.- Specified by:
getAllDims
in classFacets
- Throws:
IOException
-
getTopDims
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.
