Method Detail

getRefCountJr

public int getRefCountJr()

Returns:

the current reference count value.

release

public final void release()
                   throws IOException

Releases this index reader and potentially frees resources. In contrast to IndexReader.close() this method does not necessarily close the index reader, but gives the implementation the opportunity to do reference counting.

Specified by:

release in interface ReleaseableIndexReader

Throws:

IOException - if an error occurs while releasing the index reader.

getSequentialSubReaders

public org.apache.lucene.index.IndexReader[] getSequentialSubReaders()

Overrides:

doClose

protected void doClose()
                throws IOException
