Examples of org.springmodules.lucene.index.LuceneIndexAccessException

org.springmodules.lucene.index.LuceneIndexAccessException
Root of the hierarchy of Lucene index access exceptions. It extends the Lucene exception.
This exception hierarchy aims to let user code find and handle the kind of error encountered without knowing the details of the particular index access API in use.
As this class is a runtime exception, there is no need for user code to catch it or subclasses if any error is to be considered fatal (the usual case). @author Thierry Templier
