org.springmodules.lucene.index.document.handler.database.SqlRequest
Class which contains every informations about a sql request and its parameters.
This is used with the DatabaseIndexer to specify the request to execute. So these requests are associated with a SqlDocumentHandler to specify how to index the data contained by the returned ResultSet. @author Thierry Templier @see org.springmodules.lucene.index.object.database.DatabaseIndexer @see org.springmodules.lucene.index.support.database.SqlDocumentHandler

    SqlRequest request = new SqlRequest("select * from test");
    assertNull(indexer.getDocumentHandler(request));
