[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-3403) new ResultSetTransformer which converts a two columns of a result set into one big HashMap.

new ResultSetTransformer which converts a two columns of a result set into one big HashMap. ------------------------------------------------------------------------------------------- Key: HHH-3403 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3403 Project: Hibernate3 Issue Type: Patch Components: query-criteria Affects Versions: 3.3.0.CR1 Reporter: Antony Stubbs Priority: Minor Attachments: HHH3403.patch, PassThroughTransformer.java, ResultElementTransformer.java, resultrow-to-mapentry.rar This patch introduces a new ResultSetTransformer which converts a two column result set into a HashMap. I realised when trying to integrate it into the Hibernate package that I would have to remove the Generics which is a shame. Wasn't sure where to house the test case as there seem to be no direct tests of ResultTransformer type code, so I added a new test package and put it there. The first result column should contain unique values. Any non-unique values will cause the hash map to overwrite the previous value stored in the hash map. A usage example might be to easily convert a country code lookup table into a hashmap. The closest existing transformer AliasToEntityMapResultTransformer converts a result map into a list of hash maps contain key/value pairs for the column name / value, as opposed to this patch which creates one large map, vertically instead of horizontally you could say. "A Result Transformer which generates a map of the results. Useful for use with lookup tables or simple key value pair tables. For example, with a country codes to names table you could use the result like this: result.get("nz") would return "New Zealand"." I've attached the project I made it in, from which you should just be able to take the class files.
