  org.apache.lucene.codecs.DocValuesProducer.SortedSetDocsWithField

All Implemented Interfaces:

Bits

Enclosing class:

DocValuesProducer

public static class DocValuesProducer.SortedSetDocsWithField
extends Object
implements Bits

A simple implementation of DocValuesProducer.getDocsWithField(org.apache.lucene.index.FieldInfo) that returns true if a document has any ordinals.

Codecs can choose to use this (or implement it more efficiently another way), but in most cases a Bits is unnecessary anyway: users can check this as they go.
