C# Class Lucene.Net.Index.IndexWriter.ReaderPool

Holds shared SegmentReader instances. IndexWriter uses SegmentReaders for 1) applying deletes, 2) doing merges, 3) handing out a real-time reader. this pool reuses instances of the SegmentReaders in all these places if it is in "near real-time mode" (getReader() has been called on this instance).

Public Methods

Method	Description
Dispose ( ) : void	Remove all our references to readers, and commits any pending changes.
Get ( SegmentInfo info, bool doOpenStores ) : Lucene.Net.Index.SegmentReader	Obtain a SegmentReader from the readerPool. The reader must be returned by calling Release(SegmentReader)
Get ( SegmentInfo info, bool doOpenStores, int readBufferSize, int termsIndexDivisor ) : Lucene.Net.Index.SegmentReader	Obtain a SegmentReader from the readerPool. The reader must be returned by calling Release(SegmentReader)
GetIfExists ( SegmentInfo info ) : Lucene.Net.Index.SegmentReader
GetReadOnlyClone ( SegmentInfo info, bool doOpenStores, int termInfosIndexDivisor ) : Lucene.Net.Index.SegmentReader	Returns a ref to a clone. NOTE: this clone is not enrolled in the pool, so you should simply close() it when you're done (ie, do not call release()).
InfoIsLive ( SegmentInfo info ) : bool
MapToLive ( SegmentInfo info ) : SegmentInfo
ReaderPool ( IndexWriter enclosingInstance ) : System
Release ( Lucene.Net.Index.SegmentReader sr ) : void	Release the segment reader (i.e. decRef it and close if there are no more references.
Release ( Lucene.Net.Index.SegmentReader sr, bool drop ) : void	Release the segment reader (i.e. decRef it and close if there are no more references.
