[jira] Created: (IBATIS-273) Support generics

Support generics
----------------

         Key: IBATIS-273
         URL: http://issues.apache.org/jira/browse/IBATIS-273
     Project: iBatis for Java
        Type: Improvement
  Components: SQL Maps  
    Reporter: Reuben Firmin


Hello,

I know that JDK 1.5 support is not intended yet, so this is just a request for the future. It'd be great if you could support generics, particularly from the queryForList object; at the moment I do:

List<String> locked = getSqlMapClientTemplate().queryForList("Daemon.getLockInfo", null);

...which compiles fine, but isn't strictly valid, since queryForList just returns a List, and not a List<T>.

Thanks

[jira] Commented: (IBATIS-273) Support generics

Jeff Butler commented on IBATIS-273:
------------------------------------

The best iBATIS will ever do is return List<Object>.  When iBATIS is compiled we have know way of knowing what your return types will be.  So you'll always have to do this:

List<String> locked = (List<String>) getSqlMapClientTemplate().queryForList("Daemon.getLockInfo", null); 

This works currently and can be nicely encapsulated in a DAO object for use in the rest of your application..
