Subclasses of AtomicReader in org.apache.lucene.index

class	FilterAtomicReader A FilterAtomicReader contains another AtomicReader, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
class	ParallelAtomicReader An AtomicReader which reads multiple, parallel indexes.
class	SegmentReader IndexReader implementation over a single segment.
class	SlowCompositeReaderWrapper This class forces a composite reader (eg a MultiReader or DirectoryReader) to emulate an atomic reader.

Fields in org.apache.lucene.index declared as AtomicReader

protected AtomicReader

FilterAtomicReader.in The underlying AtomicReader.

Uses of AtomicReader in org.apache.lucene.search

Methods in org.apache.lucene.search with parameters of type AtomicReader

protected DocIdSet	CachingWrapperFilter.docIdSetToCache(DocIdSet docIdSet, AtomicReader reader) Provide the DocIdSet to be cached, using the DocIdSet provided by the wrapped Filter.
byte[]	FieldCache.getBytes(AtomicReader reader, String field, boolean setDocsWithField) Checks the internal cache for an appropriate entry, and if none is found, reads the terms in field as a single byte and returns an array of size reader.maxDoc() of the value each document has in the given field.
byte[]	FieldCache.getBytes(AtomicReader reader, String field, FieldCache.ByteParser parser, boolean setDocsWithField) Checks the internal cache for an appropriate entry, and if none is found, reads the terms in field as bytes and returns an array of size reader.maxDoc() of the value each document has in the given field.
Bits	FieldCache.getDocsWithField(AtomicReader reader, String field) Checks the internal cache for an appropriate entry, and if none is found, reads the terms in field and returns a bit set at the size of reader.maxDoc(), with turned on bits for each docid that does have a value for this field.
DocTermOrds	FieldCache.getDocTermOrds(AtomicReader reader, String field) Checks the internal cache for an appropriate entry, and if none is found, reads the term values in field and returns a DocTermOrds instance, providing a method to retrieve the terms (as ords) per document.
double[]	FieldCache.getDoubles(AtomicReader reader, String field, boolean setDocsWithField) Checks the internal cache for an appropriate entry, and if none is found, reads the terms in field as integers and returns an array of size reader.maxDoc() of the value each document has in the given field.

int[]	FieldCache.getInts(AtomicReader reader, String field, boolean setDocsWithField) Checks the internal cache for an appropriate entry, and if none is found, reads the terms in field as integers and returns an array of size reader.maxDoc() of the value each document has in the given field.
int[]	FieldCache.getInts(AtomicReader reader, String field, FieldCache.IntParser parser, boolean setDocsWithField) Checks the internal cache for an appropriate entry, and if none is found, reads the terms in field as integers and returns an array of size reader.maxDoc() of the value each document has in the given field.
long[]	FieldCache.getLongs(AtomicReader reader, String field, boolean setDocsWithField) Checks the internal cache for an appropriate entry, and if none is found, reads the terms in field as longs and returns an array of size reader.maxDoc() of the value each document has in the given field.
long[]	FieldCache.getLongs(AtomicReader reader, String field, FieldCache.LongParser parser, boolean setDocsWithField) Checks the internal cache for an appropriate entry, and if none is found, reads the terms in field as longs and returns an array of size reader.maxDoc() of the value each document has in the given field.

FieldCache.DocTerms	FieldCache.getTerms(AtomicReader reader, String field, float acceptableOverheadRatio) Expert: just like FieldCache.getTerms(AtomicReader,String), but you can specify whether more RAM should be consumed in exchange for faster lookups (default is "true").
FieldCache.DocTermsIndex	FieldCache.getTermsIndex(AtomicReader reader, String field) Checks the internal cache for an appropriate entry, and if none is found, reads the term values in field and returns a FieldCache.DocTerms instance, providing a method to retrieve the term (as a BytesRef) per document.
