Method Detail

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.

doClose

protected void doClose()
                throws IOException

Overrides:

doClose in class org.apache.lucene.index.FilterIndexReader

Throws:
