Examples of FieldInfos

org.apache.lucene.index.FieldInfos
Access to the Fieldable Info file that describes document fields and whether or not they are indexed. Each segment has a separate Fieldable Info file. Objects of this class are thread-safe for multiple readers, but only one thread can be adding documents at a time, with no other reader or writer threads accessing this object.
