@Deprecated
public abstract class FloatTaxonomyFacets
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 to taxonomy faceting,and is not intended as an extension point for user-created Facets 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 float[].

Deprecated.

Per-ordinal value.

Constructor Details

FloatTaxonomyFacets

protected FloatTaxonomyFacets(String indexFieldName,
 TaxonomyReader taxoReader,
 FacetsConfig config)
                       throws IOException

Deprecated.

Constructor that defaults the aggregation function to AssociationAggregationFunction.SUM.

Throws:

IOException

FloatTaxonomyFacets

protected FloatTaxonomyFacets(String indexFieldName,
 TaxonomyReader taxoReader,
 AssociationAggregationFunction aggregationFunction,
 FacetsConfig config,
 FacetsCollector fc)
                       throws IOException

Deprecated.

Constructor that uses the provided aggregation function.

Throws:

IOException

Method Details

initializeValueCounters

protected void initializeValueCounters()

Deprecated.

Description copied from class: TaxonomyFacets

If not done already, initialize the data structures storing counts.

Overrides:

initializeValueCounters in class TaxonomyFacets

getAggregationValue

protected Number getAggregationValue(int ordinal)

Deprecated.

Description copied from class: TaxonomyFacets

Get the aggregation value for this ordinal.

Overrides:

getAggregationValue in class TaxonomyFacets

aggregate

protected Number aggregate(Number existingVal,
 Number newVal)

Deprecated.

Description copied from class: TaxonomyFacets

Apply an aggregation to the two values and return the result.

Overrides:

aggregate in class TaxonomyFacets

updateValueFromRollup

protected void updateValueFromRollup(int ordinal,
 int childOrdinal)
                              throws IOException

Deprecated.

Description copied from class: TaxonomyFacets

Roll-up the aggregation values from childOrdinal to ordinal. Overrides should probably call this to update the counts. Overriding allows us to work with primitive types for the aggregation values, keeping aggregation efficient.

Overrides:

updateValueFromRollup in class TaxonomyFacets

Throws:

IOException

makeTopOrdAndNumberQueue

protected TopOrdAndNumberQueue makeTopOrdAndNumberQueue(int topN)

Deprecated.

Description copied from class: TaxonomyFacets

Return a TopOrdAndNumberQueue of the appropriate type, i.e. a TopOrdAndIntNumberQueue or a TopOrdAndFloatNumberQueue.

Overrides:

makeTopOrdAndNumberQueue in class TaxonomyFacets

missingAggregationValue

protected Number missingAggregationValue()

Deprecated.

Description copied from class: TaxonomyFacets

Return the value for a missing aggregation, i.e. -1 or -1f.

Overrides:

missingAggregationValue in class TaxonomyFacets

setIncomingValue

protected void setIncomingValue(TopOrdAndNumberQueue.OrdAndValue incomingOrdAndValue,
 int ord)

Deprecated.

Description copied from class: TaxonomyFacets

Set the value for a TopOrdAndNumberQueue.OrdAndValue to the one corresponding to the given ordinal.

Overrides:

setIncomingValue in class TaxonomyFacets

newAggregatedValue

protected TaxonomyFacets.AggregatedValue newAggregatedValue()

Deprecated.

Description copied from class: TaxonomyFacets

Initialize an accumulator.

Overrides:

newAggregatedValue in class TaxonomyFacets
