Constructor Detail

RangeFacetCountCollector

protected RangeFacetCountCollector(String name,
                                   FacetDataCache dataCache,
                                   int docBase,
                                   FacetSpec ospec,
                                   List<String> predefinedRanges)

Method Detail

getCountDistribution

public int[] getCountDistribution()

gets distribution of the value arrays. When predefined ranges are available, this returns distribution by predefined ranges.

Specified by:

getCountDistribution in interface FacetCountCollector

Returns:

integer array of count values representing distribution of the facet values.

getName

public String getName()

Description copied from interface: FacetCountCollector

Gets the name of the facet

Specified by:

getName in interface FacetCountCollector

Returns:

facet name

getFacet

public BrowseFacet getFacet(String value)

Description copied from interface: FacetAccessible

Gets the facet given a value. This is a way for random accessing into the facet data structure.

Specified by:

getFacet in interface FacetAccessible

Parameters:

value - Facet value

Returns:

a facet with count filled in

collect

public final void collect(int docid)

Description copied from interface: FacetCountCollector

Collect a hit. This is called for every hit, thus the implementation needs to be super-optimized.

Specified by:

collect in interface FacetCountCollector

Parameters:

docid - doc

collectAll

public final void collectAll()

Description copied from interface: FacetCountCollector

Collects all hits. This is called once per request by the facet engine in certain scenarios.

Specified by:

collectAll in interface FacetCountCollector

getFacets

public List<BrowseFacet> getFacets()

Description copied from interface: FacetAccessible

Gets gathered top facets

Specified by:

getFacets in interface FacetAccessible

Returns:

list of facets

close

public void close()

Specified by:

close in interface FacetAccessible

iterator

public FacetIterator iterator()

Description copied from interface: FacetAccessible

Returns an iterator to visit all the facets

Specified by:

iterator in interface FacetAccessible

Returns:

Returns a FacetIterator to iterate over all the facets
