Uses of IndexReader in org.apache.lucene.index

Subclasses of IndexReader in org.apache.lucene.index

`class` | `MultiReader` An IndexReader which reads multiple indexes, appending their content.
`class` | `ParallelReader` An IndexReader which reads multiple, parallel indexes.
`class` | `SegmentReader` IndexReader implementation over a single segment.

Fields in org.apache.lucene.index declared as IndexReader
`protected IndexReader` | `FilterIndexReader.in`
`protected IndexReader[]` | `MultiReader.subReaders`

Methods in org.apache.lucene.index that return IndexReader
