All Implemented Interfaces:

Accountable

public class DefaultSortedSetDocValuesReaderState
extends SortedSetDocValuesReaderState

Default implementation of SortedSetDocValuesFacetCounts. You must ensure the original IndexReader passed to the constructor is not closed whenever you use this class!

Field Details

field

private final String field

valueCount

private final int valueCount

reader

public final IndexReader reader

IndexReader passed to the constructor.

cachedOrdMap

private final Map<String,OrdinalMap> cachedOrdMap

There is only ever one cached ordinal map, but storing it in a hash map together with the field name is convenient. It enables us to have code blocks synchronized on the ordinal map even when the ordinal map is null and it makes it easy to call to Accountables.namedAccountables(String, Map) in getChildResources().

config

private final FacetsConfig config

prefixToDimTree

private final Map<String,SortedSetDocValuesReaderState.DimTree> prefixToDimTree

Used for hierarchical dims.

prefixToOrdRange

private final Map<String,SortedSetDocValuesReaderState.OrdRange> prefixToOrdRange

Used for flat dims.

Constructor Details

DefaultSortedSetDocValuesReaderState

public DefaultSortedSetDocValuesReaderState(IndexReader reader,
 FacetsConfig config)
                                     throws IOException

Creates this with a config, pulling doc values from the default FacetsConfig.DEFAULT_INDEX_FIELD_NAME.

Throws:

IOException

DefaultSortedSetDocValuesReaderState

public DefaultSortedSetDocValuesReaderState(IndexReader reader,
 String field,
 FacetsConfig config)
                                     throws IOException

Creates this, pulling doc values from the specified field.

Throws:

IOException

Method Details

createOneHierarchicalFacetDimState

private int createOneHierarchicalFacetDimState(SortedSetDocValues dv,
 int dimStartOrd)
                                        throws IOException

Throws:

IOException

createOneFlatFacetDimState

private int createOneFlatFacetDimState(SortedSetDocValues dv,
 int dimStartOrd)
                                throws IOException

Throws:

IOException

ramBytesUsed
