CacheQuery.list() returns List<Object>, which is hard to cast ------------------------------------------------------------- Key: ISPN-2826 URL: https://issues.jboss.org/browse/ISPN-2826 Project: Infinispan Issue Type: Enhancement Components: Embedded Querying Reporter: Ray Tsang Assignee: Adrian Nistor Priority: Minor Fix For: 9.0.0.Beta1, 9.0.0.Final In example for Books in https://docs.jboss.org/author/display/ISPN/Querying+Infinispan ~~ snip snip ~~ CacheQuery query = searchManager.getQuery(luceneQuery, Book.class); // and there are your results! List<Book> objectList = query.list(); ~~ snip snip ~~ This doesn't actually work. CacheQuery.list() returns List<Object> Thus, you will need to cast: List<Book> books = (List<Book>) cq.list(); But this wouldn't work... Instead you'll end up doing: List<Book> books = (List<Book>)(List<?>) cq.list();
