Method Details

clear

public void clear()

Description copied from interface: IndexReaderProvider

Closes and drops any cached resources (index readers in particular).

Should be used when stopping the index, to clean up upon error, or simply to force the creation of a new reader (refresh) on the next call to IndexReaderProvider.getOrCreate().

Specified by:

clear in interface IndexReaderProvider

getOrCreate

public org.apache.lucene.index.DirectoryReader getOrCreate()
                                                    throws IOException

Specified by:

getOrCreate in interface IndexReaderProvider

Returns:

A ready-to-use index reader, with its reference count already increased. Callers are responsible for calling IndexReader.decRef() when they are done with the index reader. Callers must not call IndexReader.close(), as the index reader may be shared.

Throws:

IOException
