Uses of AtomicReader in org.apache.lucene.index

Subclasses of AtomicReader in org.apache.lucene.index

Modifier and Type	Class and Description
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

Modifier and Type	Field and Description
protected AtomicReader	FilterAtomicReader.in The underlying AtomicReader.

Fields in org.apache.lucene.index with type parameters of type AtomicReader

Modifier and Type	Field and Description

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

Modifier and Type	Method and Description
AtomicReader	AtomicReaderContext.reader()
