## Uses of Class
org.apache.lucene.index.Fields

Packages that use Fields
org.apache.lucene.codecs: Codecs API: API for customization of the encoding and structure of the index.
org.apache.lucene.codecs.compressing: StoredFieldsFormat that allows cross-document and cross-field compression of stored fields.
org.apache.lucene.codecs.lucene40: Lucene 4.0 file format.
org.apache.lucene.index: Code to maintain and access indices.

Uses of Fields in org.apache.lucene.codecs

Subclasses of Fields in org.apache.lucene.codecs
`class` `BlockTreeTermsReader` A block-based terms index and dictionary that assigns terms to variable length blocks according to how they share prefixes.
`class` `FieldsProducer` Abstract API that produces terms, doc, freq, prox, offset and payloads postings.

Methods in org.apache.lucene.codecs that return Fields
`abstract Fields` `TermVectorsReader.get(int doc)` Returns term vectors for this document, or null if term vectors were not indexed.

Methods in org.apache.lucene.codecs with parameters of type Fields
`protected void` `TermVectorsWriter.addAllDocVectors(Fields vectors, MergeState mergeState)` Safe (but, slowish) default method to write every vector field in the document.
`void` `FieldsConsumer.merge(MergeState mergeState, Fields fields)` Called during merging to merge all `Fields` from sub-readers.

Uses of Fields in org.apache.lucene.codecs.compressing

Methods in org.apache.lucene.codecs.compressing that return Fields
`Fields` `CompressingTermVectorsReader.get(int doc)`

Uses of Fields in org.apache.lucene.codecs.lucene40

Methods in org.apache.lucene.codecs.lucene40 that return Fields
`Fields` `Lucene40TermVectorsReader.get(int docID)`

Uses of Fields in org.apache.lucene.index

Subclasses of Fields in org.apache.lucene.index
`static class` `FilterAtomicReader.FilterFields` Base class for filtering `Fields` implementations.
`class` `MultiFields` Exposes flex API, merged from flex API of sub-segments.

Fields in org.apache.lucene.index declared as Fields
`static Fields[]` `Fields.EMPTY_ARRAY` Zero-length `Fields` array.

Methods in org.apache.lucene.index that return Fields
`Fields` `ParallelAtomicReader.fields()`
`Fields` `FilterAtomicReader.fields()`
`Fields` `SlowCompositeReaderWrapper.fields()`
`abstract Fields` `AtomicReader.fields()` Returns `Fields` for this reader.
`Fields` `SegmentReader.fields()`
`static Fields` `MultiFields.getFields(IndexReader reader)` Returns a single `Fields` instance for this reader, merging fields/terms/docs/positions on the fly.
`Fields` `ParallelAtomicReader.getTermVectors(int docID)`
`abstract Fields` `IndexReader.getTermVectors(int docID)` Retrieve term vectors for this document, or null if term vectors were not indexed.
`Fields` `FilterAtomicReader.getTermVectors(int docID)`
`Fields` `SlowCompositeReaderWrapper.getTermVectors(int docID)`
`Fields` `BaseCompositeReader.getTermVectors(int docID)`
