Question

I’m refactoring some legacy code, and I keep running into this Object. I would like to get more use out of this Class, but I’m having a hard time finding an example of its use that is relevant. So far I only have found javadocs and source code. Does anyone know of a good example out there?

–Update
Wow, quick turnaround on those answers. Thank you very much. I did some more digging into the code and the ListOrderedMap is created by org.springframework.jdbc.core.JdbcTemplate.queryForList. So the description in the javadoc, “The results will be mapped to a List (one entry for each row) of Maps (one entry for each column, using the column name as the key).” makes a little more sense to me than the description for ListOrderedMap.

Answer 1

ListOrderedMap is like a java.util.LinkedHashMap that can be used as a decorator/wrapper class. If you prefer a different Map implementation than HashMap (a reference map, for example) you can add to it the preservation of insertion order.
