info.archinnov.achilles.type.TypedMap
old way Map columns = manager.nativeQuery("SELECT * FROM users WHERE userId = 10").getFirst(); String name = (String)columns.get("name"); // BAD ! Long age = (Long)columns.get("age"); // BAD ! // With TypedMap TypedMap columns = manager.nativeQuery("SELECT * FROM users WHERE userId = 10").first(); // Explicit type (String) is passed to method invocation String name = columns.<String>getTyped("name"); // No need to provide explicit type. The compiler will infer type in this case Long age = columns.get("age"); Since call to getTyped(String key) may return null, you can use the second method getTypedOr(String key, T defaultValue) to pass a fallback value @see TypedMap
